We keep reading threads wherein the driver can’t get into his Elise/Exige because the battery in the fob is dead or too weak.

I just change mine every 6 months; it’s on my calendar.

But, I decided on a tiny experiment.

I waited and, as we might expect, I had to get closer and closer to the car for the fob to work.

So, no real excuse for battery dying on us.

OH: And, carry a spare battery or two.

and, fuses

and, get a Battery Tender or similar.

The LED on the fob stays lit when the battery is low.

I carry an extra one just in case. You never know with these cars. lol

Hmm...Let's see I've had my car for 4 years and haven't changed the battery yet. And it's the battery that was in there when I got the car...which had been in the bank's possession from getting repo'd the year before.

I'm thinkin' I might want to get around to changing it :)

Is that true?? I guess I've never let that battery go weak enough.

Of course, it's smart to carry a battery or two....and fuses.

Both are light weight....

I think so. And, iirc, we're supposed to wait 10 sec to put new battery in.

SirLotus has links to alarm stuff on his posts.

I've swapped batteries on both fobs without waiting the 10 seconds, and I didn't need to reprogram either one afterwards.

Don't change the batteries on both fobs in your house.

Change one and make sure it works. Then change the other one.

You don't want to be :facepalm if something goes wrong.

Mine is from 2008, still works but I am prob pushing my luck and should change the battery asap. I am assuming that when the battery gets weaker the only warning will be that the transmission distance becomes shorter - if you are lucky.

Last week I took the Loti on a date night, got to the restaurant and the FOB would not lock the car... the LED was constant. Panic set in...

Luckily I carry a spare FOB in the boot. Fumbled around for the spare and it was functioning ok. It saved the night.

I had to resync when changing the battery... easy to do.
