Small dome on headliner
 

does anyone know what the small plastic dome is right above the rear view mirror? Thanks...TJ

Sorry about all the questions.

It is the reciever for the IR signal for keyless entry.

Ahhhh so now how do I get one since it didn't come with one and Thank You

Dealer or eBay but the dealer will need to program it for you. Some locksmiths also do the programming but they charge as much as the dealers do so it's your choice.

OK thanks for your help.

No problem, That's what we do. Jeepers helpin' Jeepers.
