I've got the cobra alarm tear drop fob and as I've read before for some others, it doesn't open the boot. I read where one person had a Cobra engineer come out and make a modification which cured it. Well I have just rang Cobra technical and they (no name as they said they are not meant to ) have emailed me the "how to" !!! Let's hope it works. Any one else with a Cobra alarm that doesn't open the boot?
