Key Fob - How Do I Replace Battery?

[LC6529]

The key fob on my 2002 SC430 is starting to act funny, when I press the buttons on it the red light does not flash until

I keep pressing and finally I get a light and the doors/trunk will open.

I suspect the battery is going dead since it is the original one.

Q: Is this something I can replace or do I need to go to the dealer?

I beleive it is a cr1216 battery, Get yourself a small jewelers phillips head screwdriver and remove the scvrew at the base of the fob, Open it up and simply replace the old battery, Reverse order to put it back together and your done. ;) Buy a couple extra batteries and keep them with the screwdriver in the glovebox.

That's what I had hoped someone would say, what I was afraid of was someone would say that it had to be reprogrammed to the Lexus.

Anyway, I got a small Philips from my model kit screwdrivers and removed the three screws and replaced the battery

(CR1616 - Duracell Replacement = DL1616) and all is working as should.

Thanks for allaying my fears!
