hi ladies and gentlemen this is Keith from my iRepair Autos and today we're
going to be talking about Mercedes smart keys and how to program them they come from
the factory from the dealership by default in global locking and unlocking
which means that you push one button and it opens all doors push another button that locks
all doors now that could be great if you're traveling with a whole bunch of
people but if you're traveling by yourself you want to program these keys
to have selective locking unlocking where opens only the driver's door and
your gas lid so please stay with me I'm going to show you how to reprogram these
keys to do exactly what you want how to reset them to factory if you don't like
that programming mode that you've just put in and yeah we're gonna make these
keys do exactly what you want hey but before we get started with this
video if you haven't please subscribe share and like this video it helps with
the ratings on YouTube so other users can see fine and enjoy the same videos
that you find helpful thank you all right before we start programming or
reprogramming or resetting anything to factory the first thing we gotta do is
we gotta find out what mode the vehicle is currently in so I'm gonna push the
lock button and the front doors all the doors are locked I pushed that once
pushing the unlock button once it unlocked all the doors front back and
trunk including your gas cover so the cuy right now is programmed for global
locking global unlocking so that's great so now what we're gonna do we're gonna
program if a selective locking so they're going to selective mode which
means that when you unlock the car or lock the car it's gonna do different
things from global entry when you're unlock it once it's gonna unlock your
driver's door and the gas flap only when you unlock it a second time it will
unlock all doors when you press lock however it will lock all doors in
selective or global entry because you always want to lock
all doors so to go into selective mode you will then hold a lot and the unlock
buttons together until you see the light flash two times now you're in selective
mode now it's just what we've just done I'm going to push the unlock button now
we've got a note passenger-side did not unlock what the driver's side did as
well as the gas flap that unlocked now to unlock all the other doors you would
press the unlock button once more unlocking all the doors including the
trunk to lock all it's smart enough to know that when you're gonna lock you're
gonna push it once and all will lock just like before
that's the selective setting mode to reset your smart key back to the factory
setting which is Global Entry global locking and unlocking you would then
once you're in selective mode you would hold down the lock and the unlock
buttons until it flashes twice then you release then to test what we've just
done we're going to unlock the vehicle and all the doors trunk unlock to lock
them back we put them back and they all lock as always everyone don't forget to
