Thread: 1999 D2 Key fob not working

Any ideas are welcome.

No. Unfortunately not my area of expertise (like most things).

Is anything else showing up on the diagnostic?

Thanks for responding Dale:

Hooking up to the Testbook analyser failed to identify any problems what so ever.

Most perplexing to me is the fact that the fob will (sometimes) actuate 2 or 3 time following the EKA code being entered. When tested with the Testbook analyser however, the BCU failed to see any activity from the fobs at all.

Due to a lack of responses to my post, I have no choice but to seek out professional assistance tomorrow. Heaven knows what this will cost me - I only hope the LR dealer doesn't take advantage of my ignorance.

Cheers

Not sure what test book does.

Have you asked anybody with a nanocom for assistance?

Thanks again Dale:

The Testbook appears to be the analyser used by the dealers & does everything bar change the oil !

Unfortunately I don't know anyone with a Nanocom, but I don't believe it to have any more functions than the Testbook. I'm actually looking at buying my own Nanocom, but that doesn't help me right now.

From unrelated posts, it appears that other members consider Les Richmond to be a fair & talented mechanic. Consequently I've decided to drop in & pay him a visit tomorrow morning. Once the problem has been identified, I'll certainly add the info to this thread.

Cheers

Your BCU may have lost it's association with your fob. I've heard of this happening before. For what reason it does this, I have no idea. Maybe power spikes from other signals being transmitted or electrical fields??

Most likely you will need to get it reprogrammed and you'll be away.

Keep us posted.

Cheers Chris:

I sincerely hope it is simply a matter of re=establishing communications between the fob & the BCU !

I guess I'll find out for sure when I present my vehicle (unannounced) to Les Richmond's garage tomorrow morning. Reprogramming sounds a lot cheaper than either a blown receiver or BCU.

Thanks again for responding.

Hi all:

Unfortunately the problem remains undiagnosed.

Andrew at Les Richmond Automotives spent over an hour trying to find the cause, but it would appear the problem is more deeply seated than hoped.

Once hooked up to the analyser, detection & even recoding of the original key fob was achieved, but functionality was again intermittent at best. We also tried to detect a number of other keys (both 315 mHz & 433 mHz), but all without success; which only adds to the confusion.

In the end all security functions have been disabled, which allows me to enter & start my car with the key. I have however lost both security & remote entry, but at least I don't have to go through the EKA code sequence (which included a 5 min. wait) everytime I want to drive my vehicle.

I now have to decide whether to throw money at the problem or put up with key functionality only?

Gotta love Lucas electrics!
