Hi, i've got a merc , but i cant open the boot.
With either the remote key fob or key.
Everything else is working central locking etc
I have a e320 2003 model, the same has happened to me. I wondered if it could be the fuse but couldn't find a fuse that managed the boot.....
This problem is identical to the other post "boot wont open electronicaly by the boot release latch above the number plate, the boot release button inside the car or the key fob! I have to use the manual key to mechanically open it now."
1998 C180- My son took the battery out to charge and closed the boot which we could not then get back into because there was no power.(**** heads at Merc need a beating) We got the boot open by placing positive battery lead to positive connector under bonnet- you can find the lead close to the fire wall above wheel arch- those leads are not hidden you will see them. Using a battery and leads connect the positive (red) to the positive then earth the other led, then use remote to open boot.
If this does not work use an axe lol
Brilliant advise, needed it today, thanks!

I had the same problem with my 1999 e class, battery was fine, but would not open boot either with remote, mechanical key or switch on centre console.
under the rear seats next to battery is a bank of fuses, should be a sheet of paper with the fuses listed attached to the fusebox, on mine i think it was number 3, took it out, it seemed ok, and put it back in, but boot opened on push button when i tried it, so assume the fuse just got out of position and not making good contact

The Key Fob needs to be syncronised to the car........Try this it works for many Mercs1....ensure the battery in the "Key Fob" is OK............Press either Lock or Unlock button for more than 1 second, the lamp on the fob will light if OK. Change battery if it does not illuminate!
2.....if battery on fob OK.......Re Syncronise the key fob to the car by:.... a brief press on either button twice and within 30 seconds turn Key to position 2 on the ignition lock
Hope that fixes it...let me know?

The key doesn't work nor does the remote key fob.
Changed my battery and boot hasnt opened since!!!!
E Class 320 - W11 model - Same problem, boot wont open electronicaly by the boot release latch above the number plate, the boot release button inside the car or the key fob! I have to use the manual key to mechanically open it now. What could it be?? Please advise
Does the key work in the boot? I wonder if the vacuum line to the lock mechanism has been somehow comprimised? ie: overstuffing items in there. And I don't think you can get in through the back seat.
