Merchandise Description

The keys are transponder electronic keys and must be programmed at the vehicle to the vehicle's computer. In most situations you can do this yourself...see programming instructions below.


Installing this lock requires programming of the electronic transponder keys. We can provide a copy of the programming procedure, but the programming is then entirely up to you the customer...we do not provide any troubleshooting technical support. If all aspects of your car's main systems are in good working order, then programming of the keys is not usually a problem..
