Code check is in the receiver module. (infra - red)

Not sure what you mean by this, but the plip in the 405 is not a transponder. You can remove the key from the plip case and use independently from the plip.No need to change locks. However if you have lost a key then the security of your vehicle has been compromised and a change of external locks may be an option that you may wish to consider. Try your insurance company!

Receiver and senders are quite hard to come by as I have found out!

Pure suggestion, although it maybe a long shot!!

Do you have a Timpson's near you (the Shoe repair & key-Cuting Place)?? I think they may also trade under the name of "Minuteman".

I noticed the other day that they imply that they can provide replacement Remote Keys - it may be worth asking in there!!

HTH

Have yoy thought about slapping your friend !!!! then get him to replace your key.

Panic over. My Missis has been round for a 'proper' look for the key which she duly found in about 2 minutes...
