Door remote control not functioning

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:

Let me know.

The problem start at once and none of the function work on the fob.

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.
