Only the one Ignition 'key' has always been used on y car. It is the type whiich does not have a replaceable battery, but is charged from the car, when in use.
Of late, the sign showing that it needs charging, has come up on the instrumant Panel, regularly.
It will now not operate the Door locks at all.
Where can I get the rechargeable element in the 'Key' replaced? The other 'Key', whiich I now have to use, works perfectky, so the problem is with the original 'Key' rather than the car.
