how to change battery in remote entry key

pjbcer · Post by **pjbcer** » 01 Nov 2009, 06:04

I have a 2003 V40 and the signal from the remote entry key is very weak and you have to be standing next to the car in order for it to work. I want to change the batter in the key fob but cannot find a way to get into it. I read my manual and although they have two pages on the remote entry key, they don't tell you how to get it open! I don't want to break it by forcing anything. Anyone have the answer?

Thanks, PJ

Welcome to matthew's Volvo Site.

This is from page 44 of the owner's manual.

Battery
Each remote transmitter is powered by a three-volt battery, type CR 2025. If the range of the transmitter is noticeably reduced, this indicates that the battery is weak and should be replaced.

Replacing the battery
1. Open the remote control by twisting a coin in the ring between the front and rear sections (leave the ring in place).
2. Replace the battery, with the plus-side upward (see illustration).
3. Reinstall the cover, making sure it is secured tightly.

Typically Volvo has placed this under "Alarm".

You are THE MAN! Thanks so much for your reply as to how to change the battery in my remote entry key fob. I have done what you suggested and it did open and I was able to access the battery.
Again, thanks so much!

You can take your keyless entry transmitter to most parts stores and have the battery checked. Most have a little battery display with different transmitter batteries and a little black box to test your battery in the transmitter. You hit a button on the tester and then hit one of the buttons on your transmitter. If it's working you should see a light on the tester come on. If the battery is weak/dead it will not light. BUT there is also a possibility that the transmitter is bad. Only way to find out is buy a battery and try the tester again. I always test before I buy or before I sell.
