Hi guys I tried to use the spare key today to open the RR but it would not do it I suspect its battery is flat opened the car the old fashioned way & it set the alarm off, I sorted that with my main key so I thought I should use the flat car key & it started fine.

20 mins journey got out to lock it and it still would not work, I am right in thinking the car charges the keys up?? how long does it normally take any ideas

If the battery in the key is flat, I expect it to take a lot longer to charge. Suggest to use the spare and main key together for a while to allow the spare to charge (it has to be in the ignition during driving for that), until it starts working again. I would suspect several hours of charging before it has a decent charge and after that maybe alternate the keys every week.

If the battery is dead or the charging part is no longer working, then you need to get that fixed of course, but I suggest to do the above first  MY 2010 5.0 SC Galway green and sand interior!!

Hi ebajema,

Many thanks, I thought as much but I thought it was worth checking, I will use the spare for a while & take the other one just in case.  Mutt

You'll need the main key for a bit to switch the alarm of I think Just keep trying the spare and see if it comes back to life before you start leaving the main key home. Good luck. MY 2010 5.0 SC Galway green and sand interior!!

I may be a bit slow here but how does a key charge itself unless there is a -ve and -ve connection on the key or it uses an inductive loop charging system?

Please forgive my ignorance if this is a feature on models later than my 52 plate

It's an inductive charging system. If you have a look at the workshop manual for the 2007-2009 in PDF, you'll see the charging coil shown. MY 2010 5.0 SC Galway green and sand interior!!

I thought this was about the key for your flat.
