If it doesn't work after changing the battery you are looking at a CIM or BCM or both had similar problems on mine.

The key lost it's programming due to weak battery / bad connection. After a while the battery recovers and re-programmes when it's in the ignitiion.

Not always mine had the exact same symptoms with all 3 of my keys all had new batteries turned out to be the BCM and CIM

Hi Paul my key's are doing the same all had new batterys in and new car battery last year, some times opens first hit but other times I stand next to car pushing button for 5 mins looking like an idot walking all round car trying to open car. BCM and CIM sounds alot of money any info on price you paid cheers, Plus don't know if any differant but every time I do get into car and start up the elec windows have to be reset as they dont go up and down with out me holding down button all the way.

A bit of card to push down the battery fixed my issues
