Ok I've been trying to find a way to fix this Central Locking system for my Renault Clio.
This is what happens: When you click the button to lock the car on you car key, it doesn't respond and the car doesn't lock/unlock, I have to go around locking it manually by putting the key into the key hole on each door and locking it...
The Lock button inside the vehicle works perfectly fine but that's only the button inside the car, not my car key.
How to fix it!
DON'T go disconnecting your battery or any other methods that you may have heard of!
1) Have you car completely switched off, remove the key from the car so that it's not inserted in the key hole.
2) HOLD down the 'Lock' button (which should be on your dashboard) AND at the same time holding down the lock/unlock button on your Car key! for 5 seconds until you hear the car lock then 5 seconds later it should unlock and the red dot light next to the speedometer turns on.
3) When that happens and the red light is on, wait 5-10 seconds then click on the Lock/Unlock button on your car key and VOILA!
Your car should lock up and you will see the sidelights on your car light up when you Lock/Unlock the vehicle.
I hope that this works for you as it DEFINATELY did for me, the locking system stopped working for me ever since I bought the car which was 4-5 years ago, if not more.
So basically the car was unlocked unless I lock it manually, finally today I decided to find a way to fix it and I SURE DID FIND A WAY TO FIX IT!
Don't go to a Renault Car Service, as they will make you pay for the repair and the repair is soo easy to do, takes under a minute, save your money and follow the instructions below, it definately works as it did with me.
