Automotive technology has revolutionized car security, especially in ignition systems. The days of simple, easily duplicated mechanical keys for under $10 are long gone. Modern vehicles are equipped with sophisticated computer systems that enhance theft protection but necessitate chip-integrated keys. These keys require programming to sync with your car’s computer, a task typically performed by a professional automotive locksmith or a dealership. However, in some instances, self-programming options are available.
Automotive locksmiths are experts in programming car keys and fobs. They use specialized software and equipment that interfaces with your car’s onboard computer via the OBD port, usually located beneath the steering column. This technology allows locksmiths to program new keys, remotes, and fobs, ensuring they are recognized by the vehicle. Crucially, locksmiths can also deprogram old or lost keys, preventing them from starting the car – a vital security measure when keys are misplaced or stolen.
For certain vehicles and key types, owners might be able to utilize self-programmable car keys. Additionally, for older car models, purchasing aftermarket programming tools could be a viable option for DIY car key programming, although compatibility and capabilities are often limited.

The shift to programmable keys by car manufacturers is primarily driven by the need to deter car theft by preventing hot-wiring. Imagine a scenario from a movie – even a skilled character wouldn’t be able to hotwire a modern car to give chase; the car simply wouldn’t start without the programmed key!
Understanding Car Key Types

Modern vehicles utilize a range of key and remote types, each with varying levels of technology:
- Key Only: These keys feature a mechanical blade for door and ignition locks, and a programmable chip embedded in the plastic head to communicate with the car’s immobilizer system for starting the engine.
- Key/Remote Combo: This type integrates both the key blade and remote functionalities. The key head houses a programmable chip for ignition and buttons for locking/unlocking doors and trunks.
- Key FOB: Key fobs are purely remote devices, lacking a traditional key blade. They use buttons to control door and trunk locks and rely on push-button start ignitions in the vehicle. Often, a hidden mechanical override key is included within the fob for emergency access.
- Proximity FOB: These advanced fobs offer hands-free convenience. Simply being in proximity to the vehicle allows for door unlocking and push-button ignition start, adding a layer of seamless access.
It is strongly recommended to always maintain at least two functional keys for your vehicle. Losing your only key can lead to a “key origination” scenario, which is significantly more expensive, potentially three times or more, than creating a duplicate key.
How Locksmiths Program Car Keys and Fobs

When self-programming isn’t possible – due to vehicle limitations, lack of existing programmed keys, or prohibitive costs of DIY tools – an automotive locksmith or dealership can provide the necessary key programming services.
Most car manufacturers in the US and Asia share their key programming protocols with automotive tool manufacturers. This collaboration enables the development of specialized software and hardware that locksmiths utilize to program car keys effectively.
Locksmiths Employ Specialized Programming Computers
Locksmiths invest in professional key programming equipment to offer comprehensive key services to their clients.
To program a car key, remote, or fob, a locksmith connects a specialized key programming computer, equipped with the appropriate software, to the car’s OBD (On-Board Diagnostics) port. This port is typically located under the dashboard. Following a precise programming sequence dictated by the software, the locksmith can program new keys and fobs to the vehicle’s system.
Several companies specialize in manufacturing car key programming software and computers. These systems often have varying degrees of compatibility, supporting different car makes and models.
Due to the diverse range of car brands and models, no single programming system can cover them all. Therefore, locksmiths who aim to provide a wide range of automotive key services must make significant investments in various programming tools.
For example, ACME Locksmith’s service utilizes different types of car key programmers in Scottsdale and car key programmers in Phoenix to cater to a broad spectrum of vehicles.
Advanced Key Programming Capabilities
The sophisticated programming software used by locksmiths offers a range of functionalities beyond just adding new keys. It also allows for the removal of keys, remotes, and fobs from a vehicle’s system. This capability is crucial in several situations:
- Managing Key Limits: Some car manufacturers, like Ford, impose a limit on the number of keys that can be programmed to a vehicle (e.g., a maximum of four keys for Fords). Locksmiths can use their programming tools to erase old, non-existent keys from the system, freeing up slots for new keys to be programmed.
- Security After Key Loss or Theft: When car keys are lost or stolen, locksmiths can deprogram those specific keys from the vehicle’s system. This ensures that the lost or stolen keys can no longer start the car or, in the case of fobs/smart keys, unlock the doors, enhancing vehicle security.

The Cost to Program Car Keys and Fobs with a Locksmith
The advanced programming computers used by locksmiths are not unlimited-use devices. Most systems operate on a ‘token’ system. This means that for each key programming procedure, the locksmith must expend a pre-paid token.
Locksmiths purchase these tokens to access the programming capabilities of their equipment. Critically, each programming attempt, whether successful or not, consumes a token. This cost incurred by the locksmith for every programming attempt is factored into the overall programming fee charged to the customer.
Certain vehicles require an additional security step during programming, involving a ‘skim code’. This code, necessary for authorization, is typically obtained from the car dealership, incurring an extra cost, often around $60. This supplementary cost is also passed on to the customer.
The overall cost to program a car key can range from $25 to $100 or more. The price variation depends on several factors, including the car’s make and model, geographical location, and the specific locksmith service utilized. Any supplementary charges, such as obtaining a skim code, will be added to the final cost.
For a more detailed breakdown of costs, you can refer to resources like “How Much Do Car Keys Cost?”
In some instances, car owners may be able to obtain the skim code directly from the dealership by presenting proof of ownership, such as the car title, in person. Dealerships often consider this information as belonging to the vehicle owner and may provide it without charge when requested in person. While requiring a trip to the dealership, acquiring the skim code independently can potentially reduce the overall cost of getting a spare key.
Important Note: Manufacturers of German cars, such as Mercedes-Benz, BMW, Volkswagen, and Porsche, generally do not share their key programming protocols with aftermarket tool manufacturers (as detailed in articles like “Order Keys by VIN”). Consequently, owners of these brands will almost invariably need to visit a dealership for key programming services, which is typically a more expensive option.
If you own a German-made vehicle, it’s worth inquiring with the dealership if you can purchase the key fob or key from a third-party supplier. Some dealerships are willing to program keys sourced externally, while others will only program keys they sell themselves. If your dealership is open to programming externally sourced keys, you might be able to save money on the key itself, even while still requiring the dealership’s programming service.
Can You Program Your Car Key Yourself?

On-Board Programmable Keys and Remotes
Certain vehicle models offer the convenience of on-board key and fob programming. Instructions for this process can typically be found in your car’s owner’s manual. It’s important to note that self-programming capabilities often differ between the remote functions and the ignition key itself. You might be able to program the remote portion for door and trunk access yourself, but the ignition key, which interacts with the car’s immobilizer system, usually requires professional programming connected to the car’s computer.
The specific procedures for self-programming keys and fobs vary significantly across car makes and models. Furthermore, self-programming may require the presence of one or two already-programmed, working keys to initiate the process.
To determine if your vehicle supports self-programming and to access specific instructions, you can consult resources like the ACME Locksmith “Car Keys & Remotes” website. By searching for your car’s year, make, and model and selecting the corresponding key type, you can often find a “Programming Instructions” tab if self-programming is an option.
Even some remote-start fobs can be self-programmed using similar methods. However, instead of cycling keys in the ignition, these procedures often involve specific sequences of button presses to achieve programming.
Pro-tip #1: If your car remote suddenly stops working, the first step should always be to check and replace the remote battery. This simple and inexpensive fix often resolves the issue without needing a new remote. Additionally, review your vehicle’s warranty, insurance policy, or roadside assistance coverage, as they might offer coverage for lost or damaged keys.
Pro-tip #2: If your car key head is physically damaged, but the internal components are functional, consider replacing just the key shell. A new car key shell consists of the plastic casing and the key blade, without any internal circuitry. By carefully transferring the circuit board and transponder chip from your old key head to the new shell and having the new blade cut by a locksmith, you can save on the cost of a completely new programmed key.

DIY Car Key Programming Using a Key Programmer

For those inclined to DIY, purchasing a dedicated car key programmer online is another potential option.
Professional-grade key programmers offer extensive functionalities beyond basic key programming, but these sophisticated tools can cost thousands of dollars. Therefore, if cost-saving is the primary motivation, such high-end programmers are not practical for occasional use.
However, more affordable key programmers are available on platforms like eBay for a few hundred dollars or less. Automotive locksmiths sometimes utilize these less expensive programmers as backup tools in case their primary systems experience issues.
It’s crucial to understand that these budget-friendly programmers have significant limitations regarding vehicle compatibility. They typically support only older vehicle models, often cars manufactured before 2005 or 2006. Before purchasing a DIY programmer, meticulously verify the list of supported vehicles to ensure compatibility with your car.
Whether an inexpensive DIY programmer will ultimately save you money depends on individual circumstances. It’s advisable to obtain quotes from locksmiths and compare them to the cost of the programmer and blank keys. However, for individuals who frequently buy, sell, or maintain older vehicles, owning a DIY key programmer could potentially be a worthwhile investment over time.
