Key Fob Programming

You will need a key fob replacement, the car, and car-specific programming process information to program a key fob. Now that you have all of those things, you can actually program the key fob replacement.

When programming a car key fob, there is no need to dismantle the car’s interior; in some cases, however, it may be necessary to access the onboard diagnostic port. This involves removing certain plastic paneling from your vehicle but fear not, these panels can easily and swiftly be put back once you have completed reprogramming.

In the hands of a professional locksmith, automotive security systems can be taken apart and reassembled without causing any damage. Once this is accomplished, our tools can be used to manipulate the car’s computer system—invalidating existing keys and programming new ones. The only downside? Built-in wait times are programmed into each device in order to discourage their misuse of illicit activities.

If the diagnostic port is not needed, you may have to employ two sets of keys or something similar. Then it’s up to you if you want a professional or DIY key fob programming job done. Most probably only one mechanical key and the new replacement key fob will suffice in these circumstances—but this cannot be guaranteed for your vehicle so do keep that in mind.

If you want to program new fobs or revoke access from lost ones, the only way is through the use of your car’s diagnostic port. However, if you have any specific questions regarding how this process works for your vehicle model, feel free to ask a service technician.

If you’re replacing your car key fob, know that while the process may differ depending on the specific model of vehicle, some general principles apply. You’ll need to have both a programmed car and an unprogrammed fob in order to start; all existing remotes must be deprogrammed first. Additionally, most fobs are only compatible with their original configured cars—they can’t be reused or repurposed for another one.

If you’re attempting to access a remote or keyless starter function on two different cars simultaneously, unfortunately, this won’t be possible. Even if the fob can somehow be reset and reprogrammed, it will only work with one car’s onboard computer at any given time. To keep everything up-to-date and in good working order, make sure that what you are doing is not invalidating your warranty or lease—so do your research beforehand! After all, being smart about it ensures that you get the most out of your vehicle for years to come.

For those mechanisms that require more than one key, you will need to procure an extra. Unfortunately, there are no alternatives available if your task calls for multiple keys; attempting to pick car locks won’t work effectively as each rotation would necessitate re-picking the lock. On the plus side, should any setbacks or miscalculations transpire during reprogramming—there is a method of canceling available.
