Any KeylessGo experts out there ?

[SargeBenz]

Has anyone with KeylessGo managed to lock a car with the keys in it ?

I managed this the other day in my 53 plates W211. I had my keys in my laptop bag, placed the bag on the rear seat, and shut the rear door. The car locked automatically, and would not open. I had to get the spare set of keys to open it.

Mercedes says that it is impossible to lock your keys inside a car with KeylessGo. I have tried subsequently to repeat the problem, but cannot. The batteries in the key are new, so that is not the problem.

Does anyone have any ideas why the car with KeylessGo would lock itself and then not open ?

It's going in to the Dealer next week for a full check, but I thought I would ask here as well.

Thx, SargeBenz

The KG system will not let the keys be locked in the car.......unless there is a problem.

I have been on the KG course and I am finding it difficult to come up with a reason why the doors would lock. If you were to do what you have done the locks are not supposed to lock.

......Was the spare in the vicinity?

Was the laptop in the bag? Depending on the position, the laptop would create a pretty good shield, which might have been blocking the KG signal.

I have KG and find it to be very effective. Twice in error I tried to lock the car with the key in and it refused to lock. Once with the key in a bag in the boot and despite repeated trys to shut the boot, as the rest of the car was locked, the boot just kept popping open. The second time I left the keys inside the car and went to press the button and nothing happened.

It appears to be easier to lock keys in a non KG car when it is part unlocked.

i`m totally agree whit Richard - KG rules.
But didn`t like the automatic door-locking - how could that happend?

It has not failed since, and I am now regularly testing it.

Alas the spare key 25 miles away !!!

Yes, a laptop was in the bag. I've had the car from new, and always kept the keys and laptop in the same bag. Never had a problem before.

On mine if you unlock the car and leave it about a minute with out opening the doors it locks itself...just my 2p's worth!

Richard,

I've had the boot pop open too when I forgot the keys were in the bag and threw that in the boot. As I have said earlier, I cannot re-create the problem. If I leave the keys in the car, and try to lock from outside, it wont.

Until this episode I thought KG was excellent. Lets see what the Dealer finds in a week's time.

I know of a small problem with the keys... sometimes the battery does make a great connection to the key and thus the key would stop functioning... I have had this on my keys with KG... sometimes I walk to the car to unlock it and it will not unlock... a quick tap on the key would solve this... so I took the batteries out, scratched the surface of the batteries to make good the connection and never had the problem again.. till new batteries where fitted again....

Anoyingly thought the rubber on the drivers door handle has split on mine... MB want about 100pounds + fitting for a new door handle as they state the rubbers do not come seperately..... :(

Other than that... KG I wouldn't have a car without it now...:bannana:

Wrap the key with aluminium folio and the car does not see it, doors can be locked then.

The laptop bag and the laptop may have shielded the key enough to make it invisible to the car. It may be difficult to repeat it if the shielding effect is "just at the limit".

Of course a temporary batter connection issue or similar could also cause something similar.

I shall try the "foil" and see what happens.

I have always kept the keys inthe laptop bag with the laptop and its never let me down before. So, as you say, it could just be at a limit for that one odd moment in time.

My own feelings are that the key is faulty, but I shall let the dealer work on the problem next week, and report back.

Superglue joins rubber very effectively.

Even if car didnt pick up key... why did it lock??

That's a good question, I thought the owner tapped the door handle to lock it where it should not have locked if the key was in the car but reading the first post again, he says "the car locked automatically". :confused:

I was sure my car locked automatically when left unattended without any keys inside. It seems to be that this only happens when the car is unlocked and no door is opened. Yet this seems to confirm that it does happen in other circumstances.

Doors are supposed to get locked automatically if unlocked from remote but doors are not opened. In any other case doors should not get locked automatically, independently if it was KG or normal car. The first case is where you might forget doors open but it does not make sense in other cases.

Of course if something goes wrong, anything can happen. I know it has happened for several other car brands even keys in place, even engine running) but so far I haven't heard any case where the car would have automatically locked doors and the key got trapped in the car. This could be the first time, although a KG car. I'd like to get a confirmation from the owner that doors really got locked automatically. I find it likely that the owner actually locked the doors when getting out (easy to do without really noticing it with a KG car). Assuming the car lost contact to the key, then there is no strange behaviour from the car at all.

How? Assuming the KG card was in the car and the car couldn't "see" it, then touching the door handle when closing the door shouldn't work, either because the car can't see the KG or because the KG is inside the car.

Does it work like that? I thought the car would not need to see the key outside of the car when you lock it, just that it does not see it inside?

If it does not lock doors from the handle without seeing the key outside of the car (as you say, and I'm sure you are right), then "my theory" explaining how the doors got locked fails.

[amwebby]

Just checked. I can confirm that the car will not lock by touching the infrared spot on the handle if it can't see the KG card.

I took the car to the Dealer today for investigation.

They tested KG fully and both keys. Alas, they could find no fault. I was shown that it is possible to leave one set of keys in the car, and use the other to lock the car. Thus leaving a set of keys locked in the car.

Of course this is no help to me. I can only assume that what happened 10 days ago was either a glitch in the system, or some form of "interference" via my blackberry, or other radio frequency technology inside the bag. However, since owning the car from new, this is the only time KG has failed. I still think the system is great.

My thanks to all the contributions.

Hi Sarge :)
I fear the only way you will ever replicate this fault is when the car is out of warranty, you are late for an appointment and the spare keys are 25 miles away. :devil: :devil:

I feel for you and I believe it's fair to say the 211 has been known to have these very rare occassional glitchs ;)

Thx John. My extended warranty runs out in 18 months :eek:

I think it's fair to say that compared to my early W211 E500 (which I sent back), this one has had no real problems. At least I have not lost faith in this one as I did with the first one.
