Need some help please. Car immobiliser/key remote that doesn't work correctly.

As the title suggests, we bought a car yesterday, a Renault Megane 1.4 P reg which has a car immobiliser worked by the key remote.
The person whom we purchased the car off told us the immobliser/remote was "tempremental" but this was possibly a little understated.

Anyway the problem is when we use the key remote to try and gain entry to the car and switch off the immobiliser it works about 1 in 10 clicks.
I thought it might be the batteries in the remote so I changed them to no effect. I also checked the wiring to the infared bit in the car (above the rear view mirror?) and that seemed ok, no loose wires.

Anybody have any ideas what to try next please ? I'm afraid I and my partner are both automotively challenged so any advice needs to be for dummies. We are also on limited budgets so any work around would be good if it's an expensive fix.

Many thanks in advance for any help given.

Is this a factory fit remote?

Have you checked the manual re re-coding as some remotes LOSE the code in 20-30 seconds upon the battery being removed and have to go through a re programming sequence in the ignition to get it working properly

Ok thanks will check that first thing tomorrow. We have used it since the batteries were changed and it works the same as before.
Would it not work at all in the circumstances you give ??

Repped for your help.

another common problem with the renault immobiliser system is water getting into the ir receiver from the aerial. its most common with clios but a lot of renaults get it. it causes poor range with the remote key.

If all else fails, look in the Yellow Pages for a local auto-electrics mechanic that will come out to you. Don't go to a dealer or you'll be ripped off. I had the same problem and found that only a new fob and software was needed.

Thanks guys, appreciated. Having looked on the Renault forum that Shengis supplied both of your points are raised.
Unfortunately I'm a bit behind the times and this is the most advanced car I've ever owned, sad but true :oops: Seems all very high tech and very expensive when things go wrong !

Anyway I'll persevere and check out all the cheapest options first.

Thanks again and rep added for your help :thumbsup:


(ps rep coming to you shengis, wont allow me yet :) )

have you checked the connections in the fob itself? Mine was down to bad solder. The trouble is if it dies completely (asuming you only have one key) you will be stuffed because as far as I know, you will have to take the car to a Renault dealer to have a new key encoded. Which is a bit hard if you can't drive it. Also I had to get a key ordered from France before the dealer could encode it..

Yes checked that when I changed the batteries and all looks to be fine. Thankfully we can still use the key (tempting fate writing that!) so no worries, YET !

I have a mechanic friend who is now on the case so hopefully will get a better result than my feeble efforts.

Thanks for your help though grumpsyi, have left you rep accordingly :thumbsup:

while you're next on the renaultforums do a search for the immo code program. its a program you can d/l and when you run it you are asked for a number. you enter this number (found on the inside of your key fob) and it will tell you your immo code. so if you are in the position of not being able to use the car because the immobiliser is stuck on then you simply enter the immo code using the central locking button (instructions with the program) and it disables the immobilser temporarily. hth but you never have to use it

oh and you can test the fob (or any ir remote) by pressing the buttons near an am radio tuned as low as it will go. you will hear click if it is transmitting
