If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.

remote key. Or, you may try placing the
remote key in the cupholder in the center
console. SeeRemote Key Operation 07.
If the vehicle will not start with the other
remote key, or with the remote key in the
cupholder, the vehicle needs service. If the

learn new or replacement remote keys. Up
to eight remote keys can be programmed to
