Also, here's a bit of useful information; I read this somewhere: next time you lock a key in your car, instead of meeting the person at the scene of the crime, try this:

• have the person borrow a cell phone
• call that cell number from any other phone
• once your connected, have the person point the cell phone toward the car
• point your key FOB at the mic on YOUR phone and press the unlock button
• The car will unlock!

I am told that that should work over any distance -- New York to L.A. or even Paris!

I haven't tried it, but hey.. it's worth a shot.

By this time, no key was inserted in the ignition or keyless go activated so the doors relocked as they should.

3. Went to trunk to put groceries in but it was locked
4. Went to driver door to get in and start the car (to get the A/C running)
5. Driver door was locked too.
6. So went back to passenger side but it was now locked

So according to this, the car must have locked itself after she put her purse in the car. When she opened the passenger door, all doors and trunk should've been unlocked. Even if she manually pushed down the locking pin on the door, the remaining 3 doors and trunk would've been unlocked. The only thing that could've happened is when she threw her purse in the front the seat, the blackberry landed on the key and depressed the lock button on the remote.

Threw the purse with key and blackberry in the passenger seat; the key was now useless due to blackberry interference.
Now here is strong possibility what happened: She was still holding on to the door handle and while closing the passenger door, accidently hit the lock button; the car would lock since it did not see the key.
Went to trunk to put groceries in but it was locked
Went to driver door to get in and start the car (to get the A/C running)
Driver door was locked too.
So went back to passenger side but it was now locked

Once a door is opened (any door) it definitely cancels out the autolock feature; I tried all sorts of combinations and the autolock executes only if no activity follows remote opening.

You can't just go up to a keyless-go car and push the lock button and it lock. The car must "see" the key in order for this to work.



I'm going with aliens at this point.

At 3pm he called me to say they figured it out; I was too busy to ask how. . . When I arrived home, I realized there was bump under the driver side mat; the key was in an envelop with the invoice; proves it can be done. . .

In this scenario it may have been possible for all doors and trunk to have opened but while she was on her way to the trunk they locked. Needless to say it’s a complex system made up of multiple RF signal transmissions to a number of antennas throughout the vehicle and any one component could intermittently malfunction because of interference.

I think pinebaron needs to talk to his dealer and hopefully their explanation may provide an answer.

I called MBUSA to try to have them open the car remotely. I chose the appropriate options in their voice operator system. They connected me to the Tele-Aid dept and the phone just rang and rang and rang and rang. After 3 minutes of continuous ringing I hung up the phone, grabbed my spare key and left to the rescue.

Sure enough, I get to the car and all 4 doors locked and her purse is sitting on the passenger seat. Unlocked the car with the spare remote, opened her purse and there lies the key. I tried for 10 minutes to lock the keys back in the car. I tried all kinds of stuff and no matter what I did, I couldn't get the key locked in the car. I did find one thing out though. If you lock all 4 doors, open the trunk, put the key in the trunk and close it, the trunk will just pop back open on its own 2 seconds later. Pretty neat.

Anyway, how the hell did she do this? And has anyone else locked themselves out of a keyless-go W211?

And what the hell is Tele-Aid for if nobody answers the damn phone? Of course, I'm not a Tele-Aid subscriber and I wondered if they would've even unlocked it for me. I could've always lied and said my 2 year old son was in the car. Seems pointless to have tele-aid, especially after today.

My other car also has keyless opening using the remote key but this beats that. My friend who recently bought a 2007 Corvette has similar features except his locks automatically when he moves out of range; MB will have none of that; safety rules etc. I imagine.

Now I have seen the Chevrolet version and that remote starting is impressive and the range is over 150 yards. You can cool off your car before you leave your building. thats cool
