with any luck it should all be back to normal and you should be able to resyc the key in the drivers door.
this procedure is refered to as a hard reset.

Hard reset underway - in basement at work - will advise...
Update - 8 hours later...
The hard reset is complete. She started up without alarms with door open and key in position 2. Unfortunately I still am unable to sync the fob. The key-in-door lock and unlock is working fine, and it is starting and driving fine. I have only had one instance of funny indicator lights lit in the morning and it was in my RF-drenched garage. Now I am unsure if I need to suspect the BeCM of being dead or dying and I think that I am reluctant to buy and clone a replacement. I have half a mind to crack open the BeCM and see if there is a family of possums living in there ("I call the big one bitey" - Homer Simpson).

Disambiguification: This thread is my BeCM/immobiliser problem. While This thread is my BeCM not sleeping and killing the battery problem. They are related, but I am keeping them seperate and cross referencing them when it makes sense.

I have been running fine for a few weeks with my new battery I have more info on the suspect BeCM. I have been parking across the street to avoid the BeCM waking in my garage and all has been well. Never showing alzeimers, always starting, always running fine, always sleeping.

Last night due to the thunder storms, I moved her back into the garage for refuge. What do you know, within 2 hours, all the indicators came on (again) and stayed on. I moved it back out into the street and into the rain and she slept again and no funny lights all night.

Whatever is causing the RF interference and waking the BeCM from sleep is also causing the BeCM to go into funny behaviour mode. This doesnt happen outside my garage?! I have tried shutting down the house mains, and I have permission from neighbours to do that to their house when they are away soon.

Thankfully Rupert is able to clone my BeCM to a donor BeCM which Andy and Paul are chasing to see if the right type is available.

I am willing to spring for the donor BeCM, but I am still wondering if another RR will sleep in my garage after 2 minutes. If it does, that means my BeCM is indeed faulty, if it doesnt, it might mean there is some hope for mine.

My goals are to park my car in my garage without problems. Doesnt seem too much to ask My continued appreciation to all offering input and encouragement.

Has anyone died in your garage?
Maybe you should speak to the local priest for an exorcism.
Worth a try?

I am away at the moment as I mentioned but when I get back I will happily be the test guinea pig for seeing if my rangey will sleep in your garage (for a short time).

You are a champ. If the house was built on an Indian burial ground, and it haunts your BeCM, Ill shout you a replacement.

I think the more likely scenario is that my BeCM is terminal. Keen to get the data point though. Should only take 3 minutes.

It seems I didnt follow up on this. Dave was kind enough to drive his RR into my jinxed garage. Alas, his normally sleepy RR was awoken in the same fashion as my own. So there is definitely a source of interference for a RR BeCM there.

It even wakes up with the RF receiver antenna disconnected so it must be strong.

I guess I have two options:
1) Find the source of the interference and rambo it
2) Buy a new improved RF receiver from LR that will not be so prone to waking

Have you thought of turning your garage into a Faraday cage? Securely earth all metal sheeting and apply metal flywire over all brickwork, windows, doors and vents, connected to a common earth stake.

Or ask the air force over to pinpoint the enemy jammer and blow it up with a tactical nuke.

Libyan forces have been at work since way back in December hey!
