Programming A Single Key
A handful of manufacturers will allow you to program a single key, even if you dont have a key that works. Keep in mind that youll still need to have the key cut to fit the ignition, which means youll need to provide proof of ownership to a locksmith.
That said, the process is much simpler than programming a second or third key:
- Insert the key into the ignition, and turn it to the on position. Dont turn on the engine, only the electronics.
- Leave the key in this position for 10 minutes and 30 seconds, and then turn it off.
- Turn the key back on, and wait for additional 10 minutes and 30 seconds before turning it off again.
- Repeat the process for a third time.
- Return the key to the on position, and it will program the key.
- Test your new key by turning on the ignition.
Key In Ignition Does Not Turn
If your key fob has a physical key that you must insert into the ignition and turn and it doesnt budge, you may have a problem with the transponder chip inside the key fob base. For some reason its not sending the security code to the car immobilizer.
This is often due to water damage or actual breakage of of the chip due to the fob falling or being crushed.

Does Programming Include A Key Cutting Service
Transponder key programming is a separate service from key cutting, but all of our technicians are equipped to do both. Programming a key will not do much for a key if it has not been cut. The key will need to fit into the ignition of the car in order to start the automobile.
The transponder chip is not the sole form of user identification. It must be used in conjunction with a properly cut car key. Just as a cut key will need transponder key programming to work in the ignition, the chip needs to have a key cut so that it can work in the ignition.
What Is An Engine Immobilizer
An engine immobilizer system is a great piece of electronic security technology which is basically a vehicle theft deterrent.
Its purpose is to prevent a vehicle from being hot-wired and stolen by a thief who doesnt have a key to start the engine. Research studies have proven there are 40% fewer car thefts since immobilizers were introduced into cars.
If youve purchased a car that was made within the last 20 years, then youve probably already used this technology without even realizing it.
The car keys that car dealerships distribute now are basically key fobs or smart keys. That is why the base of the key contains buttons to lock and unlock car doors, open the trunk, or sometimes even remotely start the vehicle.
Many key fobs on newer vehicles dont even have a physical key attached to the base. You just have to be inside the vehicle with the key fob in order to start the car by way of an Engine Start button.
