To answer your question Farnsworth28, regarding the replacement of the key fob battery. I have the keyless entry fob and I changed the battery several weeks ago after three years of use. It was simple. Just pries open the fob, take out the old battery and replace with the new one. It really is that easy. I got the replacement Duracell batteries on Ebay for £1.35 for two, including postage, so I have a spare.
