General Remote central Locking not working

[PUNTOELXBERTONE]

My Punto Remote central Locking isnt working on my punto. The key buttom seems to be working press it and it lights up but wont open the doors?? Could it be a fuse??

Is it aftermarket or OEM?

My aftermarket remote locking went twice for 2 different reasons. the central locking itself was fine (when turning the key or pressing the buttons down)

The first time was a loose connection in the door. When i pressed the button on the remote i could hear the relays clicking so knew it wasn't the battery, control box or fuse.

The second time was the battery in the remote, even though the light came on when i pressed it. The range had been reduced by quite a lot also.

So... can you hear the relays clicking?

if not, replace the battery in the remote first.

if still not, check fuses.

If you can hear the relays, check wiring.

Does the central locking still work manually?

Its a fiat Remote central Locking system. I cant hear anything and the haynes is C**P doesnt say anything about romote central locking.

It Does work manually when putting the key in the lock and turning it and locks both doors. Ive Changed the Battery but still no luck.

i don't know where the remote control box thing in the car is. If you can't hear anything doesn't guarantee that its the box because i don't know if you should be able to hear it. mine was aftermarket so might have been different.

Fuse or wiring. Could be wiring powering the control unit or could be the wiring that controls the locking and unlocking. Also worth checking earths. do you have a second remote you could try?

I dont, i only have one when i bought the car. it would be brillient to get it working as thats the only thing that doesnt work on my punto. apart from my little cousin putting a twig in the lock and cant open it on the drivers side.lol. I will have to see if i can get any info from someone like the wiring diagram for the Remote central locking that would be of great help!

would that be a seperate fiat branded remote or ones built into the keys

if it's seperate little round ones will have a remote relay in the auxiliary fuse box in the glove box side with the rest of fues and relays for wondoes central locking and fogs

if its fiat the control box is in the right hand side of the boot

to program new remotes to it you either need one working remote to open the memory and you can then program any remote you fancy to it pick them p on ebay from time to time

or the original programming code

i would be amazed if anyone still has one of the original codes for the locking on a mk1 punto

should be able to check out puts from the control box and see if it's trying to do anything with the locks it will simply be earthing one or the other small wires on the central locking relay in much the same way the door switches do to trigger it but to do this it will obviously need a power and good earth point so check these also other than this there is not allot to it arial maybe some wires to the lihts not used in the uk market

believe there is also a way to make it give you fault codes with an led on it and also a programming button iirc

ok just had a look the wiring is fairly simple power earth ignition live signal for alarm you dont have earth for lock earth for unlock

has a green led and a programing button you probably souldnt mess with untill you know how it works as even to me the programing prosedure is bludy complex

howether the led should flash on every press of a remote to give a visal confirmation of it receiving the signal

also the remote should led should flash lots of times fast if it's battery is good and only once continuous if it's bad

Cheers for that littlepip, Its built into the key. I will have a go over the weekend. hows the car anyway saw that you have given it a really really good clean up. looking good. do you know what the name of the colour is for yours as it is the same colour as mine. its probally call fiat Red or something daft just want to make sure i get right paint to paint my bonnet and bumper.
