We’ve owned our EQC for just over a month and on four separate occasions whilst at home we’ve discovered the car locked but the tailgate open seemingly of its own accord.

The most likely explanation is that I’m somehow triggering the button on the key fob and that I need to buy some jeans that are less tight, but I wondered if anyone else had experienced the same thing?

Could be but you can “lock” the key by double clicking the lock button twice the red light flashes twice and the key stops transmitting but it is overridden of course when you unlock or open the boat🙄
I often set off the boot opening with the charge cable as I run it under the car as when parked the charge point is on the opposite side to the charger ( I use an 8m cable).
Think it might be an idea to consciously keep the key somewhere else for say a week and see if that cures the issue.

This key problem happened me often too. Luckily there was nothing in the way of boot door and I was notified by good people. Your explanation is what was happening me. One solution is keeping the key in a purse, keyring, beltbag etc and don't lean in such a way as to put pressure on key front and put key front facing out away from body. You can also get a key cover to make the buttons less accessible. Like a smartphone cover.

The solution to the charging cable unlocking boot problem for me was using velcro to tidy some of the excess cable in a circle. It hasn't heated the cable much and there is less entanglement

The issue is caused as I have to have the 8m cable fully unwound and if I have been a bit careless in parking, have the key in my pocket and need the cable useable for the full 8m it has to go close to the wheels and it is moving it under the car that can open the boot.Not a big issue and I try to make sure I stay a bit closer to the chargepoint when I know I am plugging in.

Likely this boot opening can be disabled by dealer but I haven't found too big an issue either. I have the same problem and have to be careful too

Kicking to open it with heavy shopping bags is such a good feature I will put up with the occasional opening when moving the cable😉

Thank you for your replies — it’s a relief to know that it’s not just me and we’ll keep the keys somewhere other than my pockets from now on!

Hi!
Experienced same problem several times. Key in pocket.

I don`t understand why it happen.

You sat on or knocked the key button with contents of your pocket I suspect🤣

But this new key is very sensitive. Unlike the ones on the w221 and old ML.

Same thing. The new smart key is sensitive.

I too have this problem. I think it is a design defect affecting security of the vehicle. Only once has this happened in a public car park, and that time there was nothing valuable Inthe vehicle but that is once too often as the car was open to all for 3 hours. It could also happen overnight which could cause rain damage to the car. It is not acceptable. I don't carry a bag or jacket so the keys have to go on my pocket. Whilst remote opening of the boot is a bit cool it is not necessary, and I would prefer to have a secure vehicle. I am going to talk to the dealers.

Did you not get a message from Mercedes’ me the car was unlocked or tailgate open? I have an Apple Watch which is really useful as I get notifications from Mercedes’ me when the car unlocks, starts up is put on charge etc. I would say the key must have been within the car range when activated. Also do you double click the lock button if using the key to lock the car as this switches the key off though if the button is hit it will turn on again. For me it is passing the cable under the car which can open the boot if a key is near but having experienced it I am now more prepared and try to pass the cable in a different way and it seems to have resolved the issue.

No message from Mercedes me when the boot is opened, as the car is locked with the boot open. Does blue clicking the lock button only disables the Ready to drive function, as pressing the boot open both opens the boot and re-enables the key. I just heard from the dealer that it is functioning properly, and that it is effect my fault for putting the key in my pocket where it might get pressed. It would be easy to have an option to only ope the boot if the car is unlocked ( like the switch on the boot). But that would require Mercedes to listen to their customers, which appears not to be the case.

A few forums link to this unlisted (officially unrecommended) video. Could ask at a carbon fiber manufacturer such as About Us - Carbonwurks for a less cardboardy equivalent part if concerned about cardboard in key, or they can custom-make a key case with no access to the buttons, which I guess would be an officially more recommended solution, as these sensitive buttons have almost never been used by me anyway! As the custom cover might cost thousand(s) they might also agree to splitting profit with an amazon listing etc to potentially recoup the development cost or a universal cover for more makes might help too.

I took the problem to the dealers who said the boot function was operating correctly, so I complained to Mercedes. They had a fix by which they reprogram the car and fob to require a double keypress on the fob boot button rather than press and hold. This has just been implemented, so it should fix the problem. I am pleased a I looked a bit ridiculous with the key on a lanyard round my next, being the temporary solution to the problem

I have been using this type of Mercedes’ key for at least 7years ( I think the GLK was a slightly different) and I have not had and do not have any problem with them. All “button“ keys will have the potential if squashed against something in a bag or pocket to activate the car if close enough and for the radio activation that is quite a distance away. Whether Mercedes’ are worse or better I cannot say per se but I imagine they are just the same frankly as it will be OEM manufacturers who make these for all the different car manufacturers.
But Mercedes’ have found a solution which is good.Out of habit I always double click when using the keys to lock the car but at home the theft risk is extremely low ( off the beaten track and 250m from the main road and we would know if anyone turned up) I frequently leave the car unlocked and then lock from the app. So this is a non problem for me. I do wonder if keys will become obsolete in the future with just app controlled opening and closing🤔
