Good morning, I thought it was a weak battery but I replaced it yet it not it is not coming up. I decided to purchase new remote control but the wires are not the same with the ones that came with the vehicle. Could I have a diagram or pinout of the control unit?

Hi,

I have attached the wiring schematics for the keyless entry system. As far as the problem, did it start all at once? Does any function on the fob work?

Here is a link you may find helpful:

Thank you for the article that you sent. From the article, at step 3, one of the sentences ""The color motioned first is the main color", I guess that "motioned" supposed to be mentioned. I am suggesting anyway.

Hi,

Have you checked all fuses? Also, if nothing is working, I question if the keyless entry receiver is working. Here are the directions for testing it. The attached pics correlate with the directions.

If the result is not as specified, there may be a malfunction on the wire harness side.
