    Default C5 X7 replacement key problems

    My 2010 C5 X7 has the same PSA remote key button everyone else evenually has -- the buttons are deteriorating and I have trod the well-worn path of getting eBay replacement shells.

    What seemed to be an easy solution just hasn't worked. Almost at the point of buying a complete key from Citroen.

    First thing was to try to swap key blades -- in other words use the OEM Citroen key blade in the new shell. Took the pin out no problem but the blade would not budge. Had it in a vise and all. Meanwhile, the eBay key shell blade dropped out as it should with its pin removed

    So I ordered another eBay key shell, this time with the correct blade (grooves in the sides), so it could be cut to suit. The previous key didn't have the grooves, but it didn't matter because I was just going to replace it anyway.

    This new key, once cut (using my OE Citroen key blade as a template) by the local locksmith/shoe repair technician (!), will open the driver's door using the lock barrell but will not turn in the ignition lock. Slides in, but will not budge the ignition barrell no matter how much jiggling of key, steering wheel is done. I slotted the OE key in just in case the ign lock was somehow jammed but it wasn't -- key turned without any problem.

    Has anyone had these problems with replacement eBay keys and have suggestions on what to do here?

    The eBay seller is offering me another key shell to try, but I've already spent $25 on key cutting that didn't work, why spend another $25? Or does it require a specialist key cutting machine to work properly?

    My apologies, I forgot to mention... I have already taken the key back and he ran it in the cutting machine again and cleaned the key. Still would not twist in the ignition. So it seems it might be a poorly cut key.

    I think I might take up the offer of a replacement shell/blade and take it to a dedicated locksmith shop to get the fresh blade cut.

    David are you familiar with this process (getting an eBay flip key cut, dropping in the OE fob innards and away you go) and it's normally successful?

    BTW, when swapping the electrics from the old OE fob to the new eBay fob it worked fine -- it's just the new key blade not working.

    To remove the blade you sometimes need to put the blade in a vice and carefully tap the body of the key away because they are glued in

    Oh right, I hadn't realised that. Thanks -- I'll give it a try.

    Compare the original and both sides of the newly cut key, looking for any variations. Both sides should be the same and cut to the same depth as the original and across all of the groove. Rough edges you can clean up with a wire wheel.

    The blade should come out fairly easily once the roll pin is removed. Are you sure there wasn't a pin within a pin? Since the old key is junk, if it won't budge try splitting the original key blade holder with a chisel / saw to recover the old blade. If the fit in the new case isn't perfect, apply a drop of araldite before fitting the pin.

    Oh one without wisdom, can you tell us exactly where you got the replacement 3-button fob from? I too have trodden that well-worn path and all I got was a new fob that had different mounting lugs so the PCB could not be transferred, and the release mechanism for the key was different, round instead of a funny K kind of shape.

    I went to get another off fleabay but having a good look at the photos, they were all the wrong type, so I hacked it and now use a fob with new buttons but a floppy key, and a loose interior. Still works perfectly well.

    I could have got a new key cut and got one with the guts that needed re-coding, but that would have cost hundreds, for a $3 case.

    It was pointless to spend anything on a new key cut so it flipped, or even trying to swap the blade over, when the interior fitting was hacked as well.

    This the one I bought. It cost more than the ones that ship China (apparently Australian stock) but I wanted it fairly quickly and it seemed to have the Citroen badge insert (it actually didn't, like all the others I've seen from China, no badge incl). At least the remote innards fit. It's the thing my replacement remove does at the moment!

    Note that you have to tell the seller that your key has grooves or not and where the battery sits so you are sent the correct unit

    The two sellers that I had recent success with for my C5 x7 keys are:


    https://www.ebay.com.au/itm/3Button-...749.l2649#rwid

    https://www.ebay.com.au/itm/Car-Remo...72.m2749.l2649



    Neither came with the badge

    Thanks to both, looks like I need a 0523.

    This is the first evidence I have seen of a fleabay seller knowing that there is more than one type. When I told the seller of the first one I bought that it was the wrong one, he sent me another one - exactly the same.

    You can salvage the badge and stick it to the new case. If you buy a case with the battery holder and have the board with a battery, the case is easily modified. If you are swapping the blade anyway, the grove or no groove variation won't matter. If you end up a spare blade blank, you can always cut it and leave it in your wallet or concealed on the car somewhere in case you lock yourself out.

    Unless you lose your key it is impossible to lock yourself out of a C5 X7 - or a raft of other Citroens - probably the same with modern Peugeots too. If fact in the more recent models with keyless entry and start it is impossible to lock a key(and fob) for the vehicle inside the vehicle.
