This applies to cars that are too old for transponder keys, e.g. ph1 Meganes.
If the keys battery dies and the key is no longer synchronised.
What does that mean?
That means when you try and plip open the doors it won't happen and you will also not be able to start the car, like I said before newer cars have a transponder key so if the car doesn't start the keys wrong or the aerial around the ignition barrel is dodgy.
The immobiliser light in the dash will flash quickly if you try and start the car
the light is caught in action in this pic.
So what do I do?
Well you need to get the keys code.
You need to open the key to get this
thats a key believe it or not and that key ring is a girls key ring, that girl is my mrs so no comments about a love heart key ring to me please!
When you open the key this is what you will find
my finger is actually pointing to the numbers, you can't make them out in that pic due to the fact its a camera phone but the number is there, get it and write it down.
Then pop down to your local friendly renault dealer. Ask for the code, they might be reluctant to give it to you but theres a space in the handbook for it and remind them that the code is the property of the car not Renault, if they refuse to give you it or try and charge you a fortune then tell them the small claims court will come down heavily in YOUR favour.
So now you have your 4 digit code. In you fat sweaty/well manicured delete as appropriate hand.
Now you need to put it in.
Turn the ignition on, this means dash lights all on and the immobiliser light is flashing quickly.
We shall assume you have a code of 1234
press and hold the central locking button, the flashing will stop then the light will flash again.
Hold it until it flashes once
let go
press again until it flashes twice
let go
press again for 3 flashes
let go
then finally press for 4 flashes
the code is now entered
after you put the last digit in the light will come on then go off for about a second then come back on, this time it will stay on for 30 seconds.
You can now start the car.
If you wish to re-synch the plip enter the code.
When you put the final digit in the light goes out comes back on and back off again (i.e. the 30 second interval) press and hold the central locking button again and the doors should lock and unlock, remove the key and plip away at the sensor, in about 3 tries the doors should lock and unlock again.
The key should now be re-programmed and work as it should.
