I just got my '05 XKR out of storage from the winter. Everything works great - except the remote key fobs. I don't see any battery issues - it was hooked to a maintainer and even the window down-up works and didn't need reprogrammed.

I thought it was the battery, so I replaced with fresh 2032. Nothing. Got out the other key fob and still nothing.

Got on forum and found how to reprogram key fobs. I can get into the learning mode, but then nothing when I press the buttons on the key fob. Tried with door open and closed.

About 4-5 years ago my security control module went. A lot of weird things were happening - door handle locks were't sinked, strange beeping, etc. New SCM and all was good. That is until the other day.

Now everything seems to work fine. No weird stuff like when the SCM went last time. All totally normal with the keys, locks, lights, etc, except for the fobs. I took the SCM out (LJE2600AC) and cleaned the contacts, checked the antenna connection etc. Put it back in and still nothing.

I am having a hard time believing it is the SCM due to everything else working. Also, these are two fobs that I have always had and worked fine last year. Brand new Li battery in one. Am I missing anything somebody can think of?

Oh, and I checked all the fuses on top of the SCM too. All good there.

Thanks

 

Try a hard reset.

The SCM does deactivate the remote capability after 28 days requiring you to use the key to unlock the car, but it is supposed to wake up after that. Apparently yours is not waking up.

 

I have the exact same problem with my 2002 XKR. I just added the problem to the list an use the key. The only anoying thing about this is you only have 7 seconds to get in and turn the key to disarm the alarm. I tried the hard reset and the reprogramming but nothing. If you solve it I want to hear about it.

 

Hmm, what's a hard reset? I did unhook the battery and try that... with no luck.

 

Try cleaning the remote first

probably not this but the car may be valet mode lock and unlock the doors manually with the key.. just a thought cant hurt to try.
