2008 Ford Focus SES Coupe: Key Fob Battery Bites the Dust

January 05, 2009

Over the weekend, the battery in the key fob of our 2008 Ford Focus said farewell to this sometimes cruel world. Its demise seemed a bit sudden, considering the car is only 11 or so months old.

Anyway, the situation called for a new battery. The car's owner's manual provided the relevant details and instructions.

First, I made a quick trip to the drugstore to purchase the replacement battery -- a CR 2032 that was about the size of a coin. The store only had that battery in a two-pack, which ran just over 8 bucks.


Next, I used a penny to pry the key fob apart. It came undone pretty easily.

I removed the old battery, slid in the replacement, snapped the fob back together and I was good to go. The entire replacement process took about 3 minutes.

The story doesn't end there. All batteries -- even lithium batteries as tiny as this one -- are considered hazardous waste under California law, and must be disposed of appropriately. Via a visit to, I generated a list of nearby drop-off locations that accept lithium batteries.

The dead battery's final resting place will be the UCLA S.A.F.E. Collection Center, located about 5 miles from where I live. It hasn't quite made it there yet; the center is open only on Thursdays, Fridays and Saturdays, and I didn't begin this undertaking until yesterday. But when the weekend rolls around, the battery (along with a broken DVD player that I need to recycle) will be placed in the caring hands of the folks at the collection center.
