Keyless entry troubleshooting
We recently picked up a wagon and purchased it knowing the keyless entry was no good. It's now my job to figure out why and get it working for the Misses.
I started off by replacing the key fob battery and that resulted in no change. Now today, I replaced the diversity antenna as well with no change. There was a previous hatch wiring repair that doesn't look to good....I'm going to repair that soon as well. Besides that am I missing anything? Any way to test the fob or car? What fuses should I be checking? Also...I accidentally broke the ribbon cable for the red plug...any one have an idea what that is? It sheared off and I can't see where it's supposed to go. |
Small update. keyless DOES work. range is short, the button press doenst always result in an action. I ordered a proper VL2020 battery as I rigged a CR2032 in there currently. Will test more tomorrow....

I think the red ribbon should go down into the glass. The black ribbon goes up into the spoiler.
Neither of my fobs worked when I got the car, but a locksmith showed me they were both emitting signal. Ultimately, I had to replace all the bodged loom wiring into the glass, including sorting the switch, and finding out how to ping the lid with no power, and then I found that the diversity antenna was knackered, and I replaced it. Everything is now working properly. However - my red ribbon cable was OK. |
That's strange locksmith service is needed for that fob issue..

I have the same issue with mine as well. I don't want to drop $400 on a new antenna amplifier if I don't know for sure if it's broken or not. I've looked at all the wires in the loom and they appear fine but I'm not opposed to replacing them if I have to. There is no sign of corrosion or water penetration on the amplifier module as some others have shown.

This should be a good reference on which wires to trace. I had the same issue, what fixed it was the hatch wiring loom. I am now having the issues again but that is due to an imperfect job the first time.

I just wanted to add a comment to the diversity antenna issue, without starting yet another thread. My comment is: Be aware that there are two frequencies used on the E61: 868.4 MHz and 315 MHz. Make sure your replacement is the right one.
