can someone tell me how to replace battery in the key fob. I have looked at it and cannot see how to open it. I am sure the service dept would love to do it for me.

 

Take the key out of the fob You'll see a little indent in the corner. Use a coin to insert into the indent and twist. It should pop open.

 

We got the batteries replaced in both our cars at a Batteries Plus store.

 

You can buy them dirt cheap on eBay....I just throw them in the freezer until I need one.

 

Has anyone actually had a battery go dead in the key fob after a few years time ?

 

Factory remote start will use more battery power.
I'm going to change mine every year.
I'm do in April.

 

I'd highly recommend changing the fob battery at one year if your RX has remote start. Mine has longer range now.

 

I bought a pack of 5 CR1632 batteries from buy.com for $7.95 with free shipping.

 

Just ordered a 5 pk of Energizer 1632 from buy.com.

 

Good deal for 5 CR1632s. Thanks

 

My jeep grand cherokee key fob has the original battery for the last 10 years. Both of them.

 

Just don't defrost in the microwave before using.

 

my 98 grand cherokee had original battery when i traded it in for rx

my 04 grand cherokee still has original battery

 

 

I'm sure your Jeep GC didn't have a smart key or the keyless push button start - these are battery eaters. Both my 2IS & 3GS fob batteries had to be replaced at apprx 18 mos - small price to pay for the privilege of never having to take the fob out of my pocket to lock/unlock the car or start the engine . . .
