Hey THRESEA ROBERT HANEY,

Does the keypad work?
Can you unlock the car with the key-less entry code?
Is this flashing constant?

The keypad will flash if the unlock code attempts exceeds the limit for security purposes.

If the keypad is flashing but no buttons have been pressed the most probably cause is water ingress or a fault with the keypad itself.

The instructions for replacing the keypad on these vehicles are covered in replacing the upper door molding as the keypad is part of this trim.

I have attached the instructions to this post.

This fault may cause the vehicle battery to go flat if the flashing is constant. If you are happy to lose the function and want to avoid a flat battery one option is to simply unplug the keypad unit.

Hope this helps, let me know if you have any further questions.

Regards, Joe

Hey THRESEA ROBERT HANEY,

You will need to remove the door panel to disconnect the electrical connection for the key pad, the instructions for removing the door panel are attached below.
