Door lock remote batteries (keychain type remote)

Almost 5 years so far for mine, use it 4 or 5 times a day. So far, no range reduction that I've noticed. Will still work at 100 yards or so.

It may depend on several factors, but for me, I've found it beneficial to keep an extra battery in the glove compartment ALONG WITH (very important!) the requisite screw driver. At minimum the battery should last a year or two. Sometimes mine has seemed to die pretty quickly (or the range seems to be shorter but then it gets mysteriously better). Radioshack carries the batteries you'd need, at about $3 apiece IIRC.

HTH, Rebecca

mine is range reduced and requires definite button push to activate now. My other FOB is just fine. I think I may start using the other one :P

Sheldon-My 1st car with this feature was a 1999 Chevy Prizm (same car as a Toyota Corolla). Probably varies but the key fob lock opener was going strong on its original batteries (IIRC) when my wife totaled the car 3 months ago ;-)

Thanks all.
