Automotive technology has revolutionized over the last four decades, with vehicle ignition systems undergoing significant transformations. We’ve moved far beyond basic mechanical keys costing just a few dollars. Modern vehicles now incorporate sophisticated computer technology for enhanced theft protection. This advancement necessitates the use of chip-integrated keys, which require programming to sync with your vehicle’s onboard computer before the engine will start. Typically, this programming is handled by a professional automotive locksmith service or a dealership/mechanic. However, in certain situations, you might be able to program the key yourself.
Automotive locksmiths possess the expertise and equipment to program car keys and key fobs. This process involves connecting specialized programming tools to the car’s computer, usually through the OBD port located beneath the steering column. Using commercially available software, locksmiths can program new keys, remotes, and fobs to be recognized by the vehicle. They can also deactivate lost or stolen keys, remotes, and fobs, preventing them from starting the car – a crucial security measure when a key goes missing.
In some instances, car owners can program their own keys, especially if they are self-programmable car keys. For older vehicle models, the necessary programming equipment might be reasonably priced, allowing you to program your car keys yourself by purchasing the required tools. However, it’s important to note that the range of vehicles and programming capabilities supported by these affordable tools is often limited.

The primary reason car manufacturers transitioned to programmable keys is to bolster vehicle security and prevent hot-wiring and theft. Imagine a scenario from an action movie – even a highly skilled character wouldn’t be able to hotwire a contemporary car to give chase; the car simply wouldn’t start!
Car Key Identification – Exploring Different Types of Car Keys
Evolution of car keys showing mechanical key, key with chip, key fob, and smart key fob.
Most contemporary vehicles utilize one of four main types of keys and/or remotes:
- Key Only: These keys feature a programmable microchip embedded within a plastic head. This chip is essential for starting the car. The key also includes a traditional metal blade for manually locking/unlocking doors and inserting into the ignition.
- Key/Remote Combo: This type integrates a programmable chip within the key head’s casing. Additionally, the key head incorporates remote control functionalities, enabling users to lock/unlock doors and/or the trunk remotely.
- Key Fob: Key fobs are essentially remote controls equipped with buttons for operating doors and trunks. Unlike key/remote combos, they lack a visible, physical key blade for starting the car. Vehicles using key fobs are typically equipped with push-button start ignitions. Often, a mechanical override key is concealed within the fob itself for emergency access.
- Proximity Fob: Proximity fobs offer enhanced convenience with proximity-based functions. Simply being in close proximity to the vehicle allows for automatic door unlocking and push-button ignition start, further streamlining vehicle access and operation.
It is strongly recommended to always possess two working keys for your modern vehicle. Losing your only key can lead to a “key origination” scenario, which is significantly more expensive – potentially three times or more – than getting a duplicate key made when you already have a working one.
How Locksmiths Program Your Keys and Fobs

In situations where self-programming your car keys isn’t possible (either because the vehicle lacks a self-programming procedure, you don’t have the required number of existing programmed keys, or the necessary tools and software are too costly), you will need to seek assistance from a qualified automotive locksmith or a car dealership.
The majority of car manufacturers in the US and Asia share their key programming protocols with automotive tool manufacturers. This collaboration enables these manufacturers to develop specialized software and hardware that locksmiths can use to program car keys effectively.
Locksmiths Utilize Specialized Programming Computers
Locksmiths invest in professional-grade programming equipment to provide car key programming services to their clientele.
To program a car key, remote, or fob, an automotive locksmith will connect a dedicated key programming computer, loaded with the appropriate software, to the vehicle’s OBD port. This port is commonly located beneath the dashboard. By following a specific programming sequence dictated by the software, the locksmith can successfully program new key fobs and keys to the vehicle.
Several companies specialize in producing software and hardware for car key programming. Often, these systems are designed to support a range of car makes and models.
Due to the diversity of car brands and models, no single programming system can cover every vehicle on the market. Consequently, investing in a comprehensive suite of programming tools can be a significant expense for a locksmith aiming to offer broad automotive key services.
For instance, ACME Locksmith’s Phoenix key programming service utilizes a specific type of car key programmer in Scottsdale, while their car key programmer in Phoenix might be a different system, reflecting the need for varied equipment to service different car brands effectively.
Key Programming Capabilities Offered by Locksmiths
Programming software empowers locksmiths with the capability to both add new keys, remotes, and fobs to a vehicle’s system and remove existing ones. This functionality is invaluable in several scenarios:
- Certain car manufacturers, such as Ford, impose a limit on the maximum number of keys that can be programmed to a vehicle. For Ford, this limit is typically four keys. Locksmiths can use their programming equipment to erase keys that are no longer in use or have been lost, freeing up memory slots for programming new keys.
- When car keys are lost or stolen, locksmiths can use their programming tools to remove these compromised keys from the car’s system. This crucial security measure ensures that the lost or stolen keys can no longer start the vehicle or unlock doors (for fobs and smart keys), protecting the vehicle from unauthorized access.

The Cost Associated with Programming Car Keys & Fobs
While locksmiths use sophisticated programming computers, these systems are not typically designed for unlimited, continuous use. In most cases, a ‘token’ system is implemented. This system necessitates the use of pre-paid tokens for each programming attempt. The programming computer will only function and allow key programming when a token is available and used.
Your local locksmith must purchase these tokens to perform programming services. Each programming attempt, whether successful or not, consumes a token. This per-attempt cost is factored into the overall programming fee that the locksmith charges to the customer.
Some vehicle models require an additional security measure: a ‘skim code’ during the programming process. Obtaining this skim code usually involves contacting the car dealership, which incurs an extra cost for the locksmith, typically around $60. This additional expense is then passed on to the customer as part of the final programming price.
The total cost to program a car key can fluctuate, generally ranging from $25 to $100. This variation depends on several factors, including the car’s make and model, the geographical location, and the specific locksmith service provider. Any supplementary charges, such as the cost of acquiring a skim code when required, will be added to the final price.
For a more detailed breakdown of car key costs, you can refer to our article: How Much Do Car Keys Cost?
It’s worth noting that you might be able to obtain the skim code yourself, potentially saving on costs. By visiting the dealership in person and presenting proof of vehicle ownership (typically your car title), you may be able to get the skim code without charge. Dealers often consider this information to be the owner’s property. While this usually requires an in-person visit, it can be a way to reduce the overall expense of getting a spare key programmed.
Important Note: German car manufacturers, including Mercedes-Benz, BMW, Volkswagen, Porsche, and Audi, generally do not share their key programming protocols with independent locksmiths (as detailed in this article: Order Keys by VIN). If you own a vehicle from one of these manufacturers, you will almost certainly need to visit a dealership for key programming services. Be prepared for significantly higher costs compared to locksmith services.
If you own a German-made vehicle, it’s advisable to inquire with the dealership about the possibility of purchasing the key fob or key from a third-party supplier. Some dealerships are willing to program keys sourced elsewhere, while others will only program keys that they sell directly. If your dealership is willing to program an externally sourced key, you might be able to save some money on the overall cost of key replacement.
Is It Possible to Program My Own Car Key?

On-Board Programmable Keys: Programming at Home
Certain vehicle models offer the convenience of on-board key programming, allowing you to program your own keys and fobs without specialized equipment. Programming instructions for these vehicles can typically be found within your car’s owner’s manual. It’s important to note that while many cars allow self-programming of the remote control functions of the key (like locking and unlocking doors), the key’s transponder chip, which is necessary to start the engine, may still require professional programming. Therefore, you might be able to program the remote functions yourself, but starting the car might still necessitate professional car key programming connected to the vehicle’s computer.
The specific procedures and processes for self-programming car keys and fobs vary significantly between makes and models. In some cases, the self-programming process might require you to already have one or two pre-programmed, working keys.
You can easily find out if your car supports self-programmable keys and access detailed instructions on the ACME Locksmith Car Keys & Remotes website.
Simply search for your vehicle’s year, make, and model. Then, select the key type that matches your current key. If self-programming is possible for your key, a “Programming Instructions” tab will be available, providing step-by-step details on how to perform the process (graphic representation of website interface).
Even certain remote-start fobs can be self-programmed using similar methods. However, instead of cycling keys through the ignition, these procedures often involve specific sequences of button presses to achieve programming.
New Honda Key Shell
Pro-tip #1: If your car’s remote suddenly stops working, the most common culprit is a depleted battery within the remote itself. Before investing in a new remote or programming services, always check and replace the battery – this simple and inexpensive fix often resolves the issue. Additionally, review your vehicle’s warranty, insurance policy, or roadside assistance coverage, as these may sometimes cover the cost of lost or damaged keys.
Pro-tip #2: If you have a broken car key head (the plastic casing), you can often fix it cost-effectively by replacing just the key shell with a new car key shell. A key shell includes the plastic housing and the uncut metal key blade, but no internal electronic components. To utilize a new key shell, you’ll need to carefully transfer all the internal parts (the circuit board AND the transponder chip) from your old, broken key head to the new shell. After transferring the internals, have the new key blade professionally cut by a locksmith to match your original key. This approach allows you to reuse your existing programmed internal components, saving you the expense of programming a completely new key.

For those inclined towards DIY solutions, it’s possible to program your own car keys by purchasing a dedicated key programmer online.
Professional-grade key programmers, offering a wide array of advanced features beyond basic key programming, can be quite expensive, often costing thousands of dollars. Expensive Car Key Programmer Example. If your primary goal is to save money, investing in such high-end equipment is unlikely to be cost-effective for occasional use.
However, there are more affordable car key programmers available online, for example on platforms like eBay, with prices starting as low as a couple of hundred dollars. Automotive locksmiths sometimes utilize these less expensive programmers as backup tools in case their primary, more sophisticated systems experience technical issues.
It’s crucial to understand that these budget-friendly programmers have limitations regarding the vehicle makes and models they support. They are generally compatible with older vehicles. Before purchasing a DIY key programmer, carefully review the supported vehicle list to ensure compatibility with your car. Many of these devices do not support cars newer than model years 2005 or 2006.
To determine if even an inexpensive DIY programmer will genuinely save you money, it’s recommended to obtain price quotes from local locksmiths or dealerships for key programming services. However, for car enthusiasts or individuals who frequently buy and sell older vehicles, owning a DIY key programmer could potentially be a worthwhile investment over time.
