Hello, I got myself a problem,

My smartkey doesn't unlock/lock the vehicle . The LED blinks when I press the buttons. The key works only after I start it.

It stops working after car is off for 10 minutes. What could be the problem? I used spare keys but same problem. The receiver seems not work after couple of minutes.

Also got a new battery. But that didn't fix the problem.

Any help would be appreciated.

We need a bit better focus on the problem.

Is it that the key won't start the car? Or is it that it won't lock or unlock the car?

If it is a locking problem, have you checked fuses? If you have a spare key, does it work?

And what year and model is your car? Please complete your profile information.
