Yes Westy.
I lost the transponder out of my Chinese fob I bought it did not snap shut properly they must be glued with epoxy I used contact cement and it fell off my truck tailgate and broke open at night on a black road . Also beware of the Skreem system if you loose or damage these keys or the Skreem fails you will own a great looking paper weight lawn ornament. Some get angry at me because I have commented on this subject and some members can be right down nasty they pick and choose who they bully. Its like teen boys ganging up on one. Its not right but it happens. Anyway I wanted to warn you. But most here on forum are very nice and helpful. I have learned alot. Please protect your keys esp since they can not be replaced at the moment also no Skreem modules are available they say perhaps by 2020 but I doubt it. These subjects are well documented on this forum. I wish you all the best with your new toy Westy
Cheers
