I have a 1990 300e and I can't get the trunk open. Up until a couple of days ago everything worked fine. My door locks and trunk lock worked properly and I could open the truck using the key or by unlocking the doors and pressing the trunk button.

Now I can't get it open. Putting the key in the lick and turning it seems to do nothing. Pushing the button does nothing. The car does not appear to have an alarm system.

I really need some help. Thanks in advance.
