When you open it from the outside? If this is the case, try putting your key in the drivers door and turning it, whether it is locked or not. I have seen many people who keep their key fob in their pocket have all kinds of issues. So, don't keep your key fob in your pocket. If it is doing it from the inside after driving, that's a different story. It all depends on the specific conditions, if you would like to elaborate.

SOURCE: how do you disable the alarm on a mercedes benz 300E 1987

Use your door key and unlock your drivers door ... that is what disables the alarm system. Make sure that the battery is rehooked... because i'm sure you took the battery loose when you couldn't get the alarm to turn off.

SOURCE: how do i disable alarm system????

under the rf floor board in the front you will see a false panel after removing carpet. remove false panel by loosening 10 mm plastic nuts your alarm module is 1 of the 2 modules on that false floor-it should have a 820 number in the part number-if it is not obvious call parts dept. and cross reference numbers-unplug module and you won't have worry about that annoying alarm anymore-hopefully i have been helpful

SOURCE: How do I remove the door panel on a 1995 Mercedes

pull off rear mirror panel, pull off electric seat adjuster knobs, pull off plastic around door handles. Unbolt top of handle. Pull out light at bottom of door. Unscrew plastic stiker plate and remove. Unscrew lock knob to remove. Then your ready to wiggle and pull the panel up and off, be careful of the area around the door handle, you may even want to pry that area out before you begin.

How do I drive my car if the remote alarm/keyless entry keychain fob no longer turns off the alarm?

The dealer usually has a contractor that deals with remote entry systems on scheduled days. Most places like carmax do too for about $75-100. Try carmax first. I'll bet you'll save money.

My Mercedes clk when I lock the car the alarm goes

Check the door switches. They are located just below the strikers for the door latches on the B-Pillars. The are prone to breakage and can cause the alarm to go off if broken. A failing alarm siren can also cause this problem, but you'll need diagnostic equipment to communicate with the alarm computer to determine that or other problems

I have a 1992 mercedes benz 300ce and i cant get the alarm to shut off. ive tried unlocking and locking it again with all keys but i cant get it to shut off

You must turn the car on after alarm goes off. Door locking and unlocking dont work after the alarm goes off. Its like you break a window to get in anyone can lock or unlock a door thats why its tied to the ignition.

The security alarm on my 2000 CLK 320 Mercedes Benz goes off for no reason, sometimes even when I'm driving.

IF ITS A FACTORY SYSTEM U HAVE ITS A DEALER RELATEDD PROBLEM. IF ITS AFTER MARKET ITS EITHER MALFUNCTIONING OR THE IGNITION WIRE IS NOT INSTALL OR HAS LOST CONNECTION. THE THIRD SOLUTION WOULD BE THE ALARM IS IN CAR JACK MODE AND IS TRIGGERED WHEN U OPEN THE DOOR
