Question

How do you change a battery on a Pontiac keyless Fob?

Answer 1

There should be a little slot in the area where the two plastic halves come together (it'll probably be near the hole where the key ring goes in).  Just stick a coin in there, a penny should be just fine, or even the end of your car key, and then twist it.  The two halves will pop apart, and then you can pull the battery out (should be in a little clip attached to the back of the circuit board).

Answer 2

To replace the battery in the remote keyless

entry transmitter:

1. Carefully pry off the cover by inserting a dime

(or similar object) in the slot between the covers

and twist.

2. Lift off the back cover.

3. Remove and replace the battery. Use one battery,

type CR2032, or a similar type. Put the new battery

in printed side down.

4. Replace the cover. Make sure the cover is on tightly

so water won’t get in.

5. Check the transmitter operation. If the transmitter

does not work after battery replacement, it may need

to be resynchronized or matched to your vehicle.

“Resynchronization” in the Index.
