Hi there;
I got a key/remote control problem; I lost my key, after 2days I found it. It was under a heavy table, that table keeps pressing on the key bottoms continuously for tow days.
I tried to open my car of E60 E520i 7/2004, using that key but it does not work.
I used my spare key it works.
I thought the battery inside that key is dead.
My question is: Is there battery inside the remote key, if yes, How can I open that key professionally & replace that dead battery.
Any one can help.
Waiting!!!
Thanks & Brgds;

What you should do is unlock the car with your working key, then use the one that doesn't work while driving and it should charge up again.
Interesting to read about the water thing though. As ours stopped working again recently, then worked for a while, and now doesn't.

Luckily our car went in for a service yesterday and they couldn't re-sync the keys at all.
In the end, they had to replace the unit as it has water in it. Now say it won't (shouldn't) happen again.
It's bad enough having to always go to the driver's door to unlock/lock the car, but the fact that the key wouldn't switch off the alarm until it was in the ignition was a right PITA.
It was such a chore as my daughter's car seat is in the opposite corner to the driver door, so whenever she was in the car it meant getting her to come round to my side of the car to wait in safety, unlocking it, having the alarm go off, sticking the keys in the ignition, taking her around to the opposite side, putting her in, then going round to the driver's side again to get in.
And as for getting her out it was equally problematic. No wonder we were all so much fitter in the old days.

I think my car is suffering from this same issue. Where is the transmitter located?
And have you ever noticed how holding the key against your head and clicking the remote lock / unlock really extends the range of the key. I cna open / ;lock the car doing this from at least double the range.(just a fun fact)

Couple of questions:
1. Where can I find the transmitter/ receiver?
2. Is it easy enough to change, if needed?
Many thanks
Rahul

I believe the Key Antenna and receiver is under the Spoiler over the rear window?. Looking for validation from others. Check realoem.com J

My keyless entry also stopped working mysteriously. After a lot of searching this is a very common problem. The transmitter under the spoiler COULD be damaged, but another very common issue is severed wiring leading to it that runs above the headliner and through the hinge point of the hatch. That is what it ended up being for me, and I was able to fix it for about $30 with some silicone wire, solder, and a Saturday. The diversity antenna itself is around $270. Here are some helpful pieces of info I found to investigate the possible wiring issue.

I also left the boot open in the rain yesterday and now my central locking remote is not working. Does it dry out, or do I need to replace the unit?

I would suggest popping the spoiler off and getting the plastic cover off the antenna amplifer - it's not that difficult to do, and you can spray down the circuit board with some electrical contact cleaner. You'll probably find corrosion on some of the terminals and pins. If you can't get it working, next step is a replacement. I've had to do mine twice now - 2010 model.

FYI, if you do have to replace it, get one from a 6 series. They have a different part number but fit and work identically. I did this because on eBay the E61 antenna amplifiers were extremely expensive and yet the 6 series ones were much cheaper.
