Key fob battery

[stuz88]

My car is 4 years*old, 30,000 miles only, and recently I had to change the batteries in both key fobs within a few months of each other. What surprised me is the 3 volt battery read 2.8 volts in each case. I would have expected that the voltage would have to fall to say 2.5 before they would give up. Anyone else share this experience?

New 3V batteries will read 3.4 - 3.5 V. 2.8 might not be completely exhausted but it's close. The remote might need a higher voltage to operate.

stuz88,

Do you remember what was the marking on the battery?

Thanks.
Now the question is how do I open that key fob?

EDIT.
Never mind, found it on YouTube.

remove metal key, insert in the pry slot, pry.
