Hello together We have been stolen an electronic key from our W463 (2003), and our concern is that if we necessarily put the vehicle back at the same place where we were stolen, that the G can then be driven away in the same way. This would certainly reduce further insurance benefits. If the still existing electronic key can be reconfigured in such a way that the other one no longer works and we easily imitate a second one. Thanks for the brief clarification! MiKoX
