How To Open Mercedes Door With Key

mattsinfield

Hi,

We recently bought an A170 Classic SE '55 Plate. We've had a couple of issues with the remote fob failing to unlock the doors which we've traced to the wireless network in the house - changed the aqueduct and then the remote started working.

However, while we had this problem we've tried to use the Emergency Central to open the drivers door which so far we've been unable to practice. The key inserts and we can quarter-plough either style earlier meeting stiff resistance but this doesn't unlock the door. An ex-MB garage foreman has said he thinks there is a technique around holding the door handle open once or twice only the online owners manual makes no mention of this.

Can anyone enlighten me as to what I'm doing wrong or is it that I need to use 3-in-1 with PTFE every bit metioned in other forum posts (possibly with a bit of muscle with grips)?

I oasis't washed this so far in case I'one thousand beingness a fool and missing something obvious and wind upwards making the situation worse

Thank you,
Matt

Employ WD40 or penetrating oil if you want a fighting chance of freeing the lock… if it is seized. How virtually the kicking lock?

Edit; Does the primal plow a full quarter turn either way.

Hold something that vibrates on the key, this should help to let the levers drop downwards over again

Don't know if yours works like mine, but I have to put in emergency key in driver's door and turn anti-clockwise and hold information technology there (Clockwise for RHD I believe), and then apace pull handle twice. The push pops upwards - you can so open door after turning key back to vertical.

Its either that or a can of WD40

Thank you for the quick replies. Yep the key tin can quarter-turn either manner earlier meeting resistance. Unfortunately the Hatchback doesn't have a transmission lock of its own. I but tried the clockwise handle-pull twice advice and no go at that place.

Its sounding like lube and vibration then!

The fact that the fundamental will enter the lock and brand a quarter turn means the lock butt is not seized, the problem is farther inside the lock.

I don't know exactly how that lock is removed on an A form. If it tin can be removes in a similar fashion to a W202 then the vacant opening tin can be sprayed with WD40 this may or may non solve the fault but worth a try if it is every bit simple a job as a W202.

Use WD40 or penetrating oil if you desire a fighting chance of freeing the lock… if it is seized. How about the kicking lock?

Apologies for the slow respond - been abroad for work. The mrs says that the remote cardinal fob now no longer unlocks the auto (it'southward not wifi interference as that'south now off). Her stance is that if she uses the car daily all is ok and if it's left for a couple of days the chances of opening drop considerably.

So now I have two problems:

i. Emergency key won't open the door - tried the lube+vibrating to see of the lock has seized and also simply in example there is no mistake (but user error!) plow and pull handle rapidly twice. Neither seems to work.

2. The remote fob doesn't unlock the central locking organization. Friends of friends of.. etc. advise that a new fob is the only cure at £220!

I'k existence driven to distraction past this and then any pointers would be very much appreciated.

2. The remote fob doesn't unlock the fundamental locking arrangement. Friends of friends of.. etc. suggest that a new fox is the but cure at £220!

Can y'all describe what blazon of remote you have and how many buttons it has?

"The remote play a joke on doesn't unlock" …does that mean that the remote will still lock?

Emergency central won't open the door - tried the lube+vibrating to see of the lock has seized and also simply in case there is no mistake (merely user error!) turn and pull handle quickly twice. Neither seems to work.

It's a mechanical action, more of a clasp than a pull every bit it has to shift the lock mechanism. Not sure exactly how it works but it's similar the outset pull engages the mechanism and the 2nd one lifts the lock. Both done after the key has been turned (i.eastward. don't turn the cardinal and pull the handle at the same time, just turn the fundamental and leave it). If you don't feel any resistance on the handle and so something is wrong.

It's a two button fox with the unlock the beneath the lock button when the play tricks os pointing at the motorcar. with regards to whether the fox tin lock the car even if it can't lock. Well that's a scenario that's hard to examination as I couldn't unlock information technology. When the play a trick on does work it will both lock and unlock.

Yesterday when it stopped raining the fob started working (unlock/lock). If information technology is affected past altercation and then I'one thousand wondering if in that location is some class of signal force problem.

I'll endeavour the handle squeeze with the emergency key tomorrow every bit well as mail a movie of the fob.

Thank you.

It appears every bit though the fob just doesn

Take you tested the remote fob with a digital camera as described in postal service #11 to a higher place?... or can yous encounter the picture in post #11?

Aye, I can come across a short white low-cal from the fob on pressing either open and close buttons when looked at through the viewfinder of a smartphone camera. The fox is of the type on the pic below:

With that key yous could attempt a re set, insert the key into ignition and press any button on the key twice within 4 seconds

mattsinfield

Only done that, the just trouble is that I don't know if its helped or non. For the past few days (since it stopped raining) I've been able to both lock and unlock the central locking past the remote fob. After the reset I still can.

The unlock drivers door or all doors by property both buttons works for 4/5 seconds works too.

Notwithstanding, yesterday the 5th door stopped opening i.east. unlock with play a trick on and try to open the boot by pressing the finger-contact doesn't unlock the kick.

Lastly (tale of woe here), I've tried the emergency primal unlock without success. Tried both quarter-turn clockwise and two squeezes without affect and the same anti-clockwise. The pics beneath show the primal positions.

Thanks in advance.

It could be a faulty motor for door 5

mattsinfield

How practise I check for faulty motor vs. dodgy contacts?

Thanks
Matt

If all the other doors are working, then information technology but leaves this ane, the motor needs to exist checked with a meter to meet if 12v is getting to the motor when locking takes place
