Hi,
First time on forum, so please excuse,
I have 2 key fobs for my R reg 1.4 megane 1 hasn't worked 4 years (although has new bat & red light comes on) now other is acting up & wont let me in/start car(this also appears to be working with new bat).Is there a way I (husband) can get around this or does he need to buy me a new key fob?

Sounds to me like the second fob is goosed if it no longer starts the car (transponder code wiped)

Does the other one start the car? I sure hope so for your sake.

If not, you may be in a pretty poor position and will need to contact Renault dealer to see if a new key can be ordered (should be OK but will cost you a few bob indeedy)

The other may resynch for unlocking the doors (if that's it's only problem), search the forum using the search feature for the correct procedure for your car, do both plips at once, the second will more than likely not work but the first may start working again as it may only need resynched to open the doors provided it starts the car.

Renault recommend using keyfobs in an alternating fashion, week about, as the unused one will eventually go out of synch as most remote keyfobs use a rolling code system, beyond a point the code will be too far out of synch if the keyfob has been sitting in a drawer too long and will no longer operate the locking. A non-starting situation cannot be caused by loss of synch, only central locking operation is affected by this.

Everything I have said is assuming you have remote central locking from a button on the keyfob.

hope this helps/clarifies things for you.

It is also remotely posssible that a blown fuse(s) has caused the second one to stop working, please check your cars' fusebox for blown fuses before you do anything else!!!

It is unlikely to be the immobiliser at fault (unless it's fuse has blown) but always a possibility just the same.

Not sure how a blown fuse would affect one key but not the other.
I have a cobra alarm that will lock/unlock my doors while enabling/disabling the alarm- one of these keys went out of synch a couple of years ago, reregistering the key with the alarm sorted it.
The renault keys have never gone out of synch though. I know the keys are linked to the immobiliser circuit on my 02 Clio- cutting a spare key from a key cutting shop won't let you start the car with it unless it is touching one of the originals.
If your Clio is fitted with an immobiliser try the link http://www.bba-reman.com/content.asp...ergency_recode or talk to your renault dealer about reregistering the keys- it shouldn't cost too much, just normal rip off levels

OK, poor wording, one already didn't work at all......you follow?

I can see how you thought I meant it that way..... deary me.
