Intelligent access key (ia key)
Your vehicle is equipped with two intelligent access keys which operate the power locks and the remote start system. The IA key must be in the vehicle to activate the push button start system.
The IA key also contains a removable mechanical key blade that can be used to unlock the driver door. To release the mechanical key blade, slide the release on the back of the transmitter and pull the blade out.
Your IA keys are programmed to your vehicle. You cannot enter or start your vehicle with an unprogrammed key. If you lose one or both of your IA keys, replacements are available from your authorized dealer. For more information on programming replacement IA keys, refer to the SecuriLock passive anti-theft system section in this chapter.
Note: Your vehicle’s IA backup keys were issued with a security tag that provides important vehicle key cut information. It is recommended that you keep the tag in a safe place for future reference.
