Title: Misbehaving Keyfob
Post by: rdfcpete on February 12, 2011, 05:47:01 pm
Had a funny experience earlier with my key fob. It's the one I've used since I've had the car so it's covered at least 24k miles in 20 months with me, possibly up to 78k if the previous owner used it as his/hers main one too.

Anyway I'd locked the car parking outside a friends. Came back out the house later on and the car simply wouldn't unlock pressing the unlock button on the fob. I tried holding it down, pressing two or three times in succession numerous times, yet nothing happened and the car wouldn't unlock.

After a minute or two of small disbelief, I realised the boot button worked and opened the boot with the rest of the car doors locked (its a 3 door).
I opened the car via the drivers side door lock and of course the alarm started singing away  :pomppomp:. I closed the door and tried disarming the alarming using the unlock button, with no luck. I put the key in the ignition to disable the alarm then shut the door + locked the car. So, all the buttons worked except the unlock button.

I fortunately have a second keyfob so I'm on that now and running it as the primary keyfob. Is it simply the battery is dead or low on the other keyfob - i.e. is that how it tells you that it's low, or is there another problem with it?

Thanks.

Replace the battery from fob 2 to fob 1 and see what happens first, could just be low transmittion due to a weak battery  :smiley:

Thanks VC.

Assuming it is the battery (I can't see what else it would be and I'm battling to take the two fobs apart now to swap the batteries), which battery type is it I need?

I understand they can be had for as little as £4 so it's hardly an expensive gamble  :happy2: Cheers.

I've been informed that a Sony CR2032 battery will fit, is that righto?  :smiley:

Could the key be out of sync from the car? A similar thing happened to me a few months ago
