Key battery

[Lizzi.Redmond]

I need to change the battery in my key fob as my car keeps beeping at me, is this something i can do myseld or do i need to go to a proper car dealership to get this done?

Can anyone help me?

To replace the battery, remove the screw then unclip the casing using a coin at the ring. The battery is a CR2016 3 volt battery and I think I bought my last one from Sainsburys, but most places that sell batteries should have them e.g. Wilkinsons. Should only cost a quid or two. Your Peugeot dealer would sell them of course, and should be able to change it for you if you're not confident enough.

By the way the keyfob has a transponder chip inside it. Make sure it doesn't fall out while you've got the key apart, or if it does put it back in properly.

If the remote control does not work after the battery has been changed, reprogramme the remote control:-
a. Switch off the ignition.
b. Switch the ignition on again.
c. Press button A. (The bigger of the 2 buttons that you normally press to lock the car.)
d. Switch off the ignition and remove the remote control key from the ignition lock. It should now be working again.
