@ peterzoom
You are doing the correct thing .. rotate the keys , the system is based on a rolling code .. if one key is not used in a long time it falls " out of sync " .. too far behind on the code advancement and will no longer work .
The batterys in these .. i know them off by heart .. CR2032 .
Porsche do NOT make these batterys .. a third party supplier does . any battery listed as this model number is acceptable .
manager as usual is not living upto the standards that Porsche would like to set and indeed i would expect they would be rather annoyed at comments like this from him .
I would also add .. a manager is NOT an ex mechanic .. he's a pen pusher who really has no idea how a car works .
Simple answer to that comment .. my solicitors will chat with yours in court if that's your answer and i will also be talking to customer services about your comments and we will see what they have to say .
Throw in the usual comments about ill never buy another Porsche if you speak to customer services and it will soon be sorted .
my feeling .. the circuit boards in these are perhaps not brilliant .. i suspect it's nothing more than a broken solder joint .. but thats still a new key head to fix as no mechanic will attempt to find the fault .. it's just not cost effective im afraid .
if i was going to blame you in any way .. you have large fingers / thumbs and apply too much pressure on the buttons and that is the reason it has failed
lol .. fobs ain't what they used to be if this is the case .
Basically you have used it as normal .. it has packed up .. see what response you get from the OPC but if your not happy then please .. ill say it again .. please phone customer services and explain your problem ..
OPC will give you their number should you request it .. that alone will send a few shock waves down their spines !!
