Peugeot 306 remote key - FP
My other half's 306 (V reg) has what I assume is an infra-red remote key (the one with a red light next to the buttons). Batteries have never seemed to last very long, but the ones I replaced last week have already failed. There seems little point in just putting in new batteries every few days.

Questions: Is this a fault with the key I can rectify myself? If I buy another key from a Peugeot dealer does it cost an arm and a leg? (I presume a new key can be programmed to the car's sensor.)

Any other thoughts gratefully considered.

Seems a common problem with the 306 keyfob.

Some info here may or not help.

I'm *sure* there are some other threads as well. These are just a couple I found using the forum search (where you log in/out.

The (two) batteries recently failed in the primary (most used) key of SWMBO's ten year old 306 Sedan, and judging by the total absence of marks in the head of the screw that holds the two halves together, it was the first time they had been replaced! Mind you, the car only covered 14,000 summer miles during the first 'eight years and a bit' of usage, and we've added 12,000 in just under two.

The batteries in the lesser used secondary key also appeared to fail last year, but in fact, the cause of failure was simply surface corrosion on the contacts, as indicated in the first of the two links in DD's post.

On the subject of battery life, although the power drain in question is miniscule, I have a slimline 'credit card' calculator purchased in 1984 that is still on the original battery!

I think there is a deeper problem here. I just bought 4 new batteries for my primary key and spare. The primary ran out today after not very long at all - maybe 3 weeks (so I had to drive home with the alarm going off - not very funny!). When I got home I got out the spare, which has been sat in a box untouched - to find it dead also. These were brand new duracell batteries so I cant understand it.

The imobiliser works off either the keypad or the transponder key.

The alarm isnt connected to the imobiliser, so it is possible to start the car with the alarm armed if you can disarm the imobiliser.
