hi. I add new key 2006 e350  w211. It work fine but 15 minutes later no thing happen when insert key. Both original and new key not response. I thought might me bad eis or flash. Replaced with another used eis, same part number. Copied eprom from original to used. car started fine but same thing happen again 15 minutes later.I read out eprom then write back the same dump then key will work again but again same thing happen 15 minutes later.Could someone tell me where is the problem? At this time I re-read and write again eprom then started the car with only original key, don't touch the new key and thing is ok.I assumed the new BE key is bad but then why original key was not response as well? If harsh was bad then why write back the same dump that I just readed make it work. Thank you
