Keyless entry module.

[Super-Merc]

Hey all, it's been a while but I still have my 2003 MM.
I am finally home long enough to attempt to repair the keyless entry module. This thing has plagued me for years. Is anyone able to replace the relays or have a source for them? I have I apart and would really like to have it working again. I did a search but can't find anything relating. I sent one out to a fellow on the site years ago but don't know if he is still around. I have the relays out at the moment. I bought a used one but it quit unlocking the doors a short time later. I already replaced the actuator twice.

Ideas? Thanks for reading.

I'll see what I can find.

Are you sure it's the relays?

[Super-Merc]

Yeah, unfortunately pretty sure. The door wires are all good and changed the actuator twice.
Thanks for looking for me!

How many relays are there?

[Super-Merc]

There are 2 of them. I believe one works the driver's lock actuator and the other one works them all.

Search for Potter and Brumfield Tyco V2R-1020.

If you need someone to install the new relays, let me know.

Good Luck!

Make sure, when swapping out the DDM, that you replace it with the exact part number..
they are on eBay, I’ve sold 100s of them.
typically they are less than 40 bucks

I've found the problem to be that you must hit the numbers extra hard. My black has this problem.
At night so you can see the interior light turn on, hit the numbers with something hard or your key.
If the light goes on, it works. I've never tried replacing the keypad, so I can't tell you if that fixes the problem.
