Hey guys. Ok so the central locking on my mk1 leon unlocks the rear doors when it feels like it and sometimes takes 3 turns of the key to unlock the rear doors. Any ideas guys? Also the car come with no central locking fob so would a after market one be easy to fit? Anyone fitted these to a leon? Cheers guys
Mk1 leon central locking
- Thread starter Leondave
- Start date
common fault on the leon is the central locking modules fitted in each door, you can by copies off ebay for around £20 worked for me.
Pulling the handle twice is probably down to the cable tension been incorrect.

Also could be due to them being locked.

Mine seems to be temperamental - just repeatedly press the unlock switch until it disappears seems to work fine... although i am not too sure this is a robust method.
Cheers guys. Is the cable tension on the inner door pull adjustable? I thought it may be down to the lock mech knackard and it only unlocking half way? Had a mk6 escort that had dodgie door locks.when i pulled them apart a peice of plastic was bust inside jamming it. Ive ordered a remote locking kit. Just need the colour codes for the lock and unlock wires 
No Haynes manual for the Leon, look up a MK4 Golf one and it will point you in the right direction.
Also, with regards to troublesome locks, there is endless information on Google and the Search on here.. I wouldn't even bother trying to fix them, just replace them as they WILL fail at some point locking you in or out of the car.
They are a well known weak point with the cars that use this type of lock.
You will need to strip down the doors to remove and replace anything or the whole module, so you will also need to reseal the door carrier panel too. Which is another job that is common to be done.
90% of Leon owners will have already done this, and the rest will be needing to do it in the coming years.

I did mine 2 weeks ago, and my friend did his last night

The inside handles need to be pulled twice to open the doors, its a safety feature - the doors automatically lock above 15 - 20 mph to prevent you opening the doors while travelling, then when you stop you have to operate the door handles twice to open (unless you switch off ignition and remove the key, then the doors automatically unlock)
Some models might not have that activated as standard though, I know it can be enabled with vag com, but that defo sounds like what's going on in regards to the rear door pulling twice.

My car doesn't have this and my rear doors started to play up resulting in the handle needing to be pulled twice.
It's a sure sign of the locks on their way out as the mech isn't fully cycling through the actions when the module is activated.
If the car doesn't have the speed locking then get the modules changed out whilst you can still get the doors open, it's a bollock of a job to get eh doors open when the modules fail and they dead lock.... trust me.. it's what happened to mine.

Yeah, that's true. Mine wasn't locking the doors while driving and one time went to the SEAT Dealer to do a common revision and came back with automatic central locking above 20Km/h.

cheers guys. tbh the amount of reading ive done on these door locks is starting to make my eyeballs bounce lol. so to recap.......... drivers door unlocks and locks fine with the key. no fob. the passenger and rear right door doesnt open most of the time unless the drivers door lock is unlocked at least twice or the unlock button pressed on the drivers door inside. the boot sometimes doesnt lock when the drivers door is locked. would it be worth buying code reader and see if it flags up any fault codes? so is it likely that the passenger and rear door locks are stuffed and need replacing or is the module likely to be kippered too? either way if the locks are knackard im guna need to change them when i fit the remote locking which turned up today. cheers for the help guys
I don't think the locks would cause the issue, seems more electrical to me which would point to the module, strange how it's more than 1 affected though.
Don't take my word for it tho, I'm sure there's other people with greater knowledge on the subject.

Hi are the locks intermittent? Some times they will open with one turn of the key and some times not? Or do they only open from the inside? I would put it down to bad door locks, as the other rear door is opening fine... The locking signal is therefore going to the other doors or else it wouldn't unlock at all.... After all it's always passengers doors that break first as no one cares about your car and the doors get slammed all the time..this is what breaks the solder on the circuit board, there for it works then it doesn't... Cheers. Reggie
The mk4 Golf locking system is identical and I know for a fact that information is in serious abundance regarding these online.
