Problem With Remote Entry Key Fob?

[bruno]

My repair was free! Those cheap clips were all broken in both my keys thus disabling my remote lock/unlock feature.

One of my CenCalLX club members simply opened up them up, put some paper inside to put pressure over the batteries and both fobs work like they are brand new!

I had my '05 300C for 18 months now, one remote never worked. After dropping the one i use for the last time it stopped working. i opened it up, and saw the bad solder joints. i soldered 2 on this remote, then opened the other remote and saw that it had the same problem. After soldering both, i tried them, but no luck. i put the batteries on the voltmeter, and they were both dead. it looks like they shorted out when the clip shifted when the solder lugs broke. After getting 2 new batteries, (3 pack for $11 at radio shack) they both work fine. So be sure to check the batteries after you fix the solder problem.

Mine was in terrible shape and I just decided to replace as my FOB was in kind of poor shape to begin with, so just an FYI, OEM FOB is pretty reasonable on transponder island, had it for $80.

I just recently had the same problem with my RKE battery so I sodered it back together and it still didnt unlock the door. So I unlocked it manualy open the door alarm went off I just put the key in the ignition and turned the car on now it works great. Hope this helps....

Finally had to fix my broken keys. Tired of the alarm going off when I open the door.

Cut a piece of copper wire and shaped it like the battery bracket. Then soldiered the copper into the two holes in the circuit board. Next soldiered the stainless steel bracket back onto the base against the copper wire. Put everything back together with a piece of pressure foam on top of the battery bracket to hold / pressure everything together.

Desiree, both of my key fobs broke in just the way you described. I resoldered the cold joints and they both work like a champ now. Thanks a million.

Thanks so much for the detailed description. I was able to solder one of my remotes
and get it working OK. The other appears to have the same problem.
A great post - thanks again!

I have soldered mine at least twice and still cant get them to work. Will try replacing the batteries again. As for new ones, I saw one post about a replacement. I also saw a replacement key that required both original keys to work in order to program the new one. Otherwise, you would need to go to a locksmith or Chrysler to do it. Is this true?
