KINDA like this, I had to search to find when I originally posted the tie wrap thing, couldn't find it, so took another pic..
mini 4" tie wraps last about 3 years, and then pop, but when it does, it's in your pocket, so no big deal...
works great, and I attach the associated keys, like lock tool for Garmin, helmet locking cable, trailer locking cable and locks, etc., to each fob... and as they are in pocket, one in my Stich side jacket pocket, and one in pants pocket, no big dealeo... I do use the one from my jacket pocket to open the gas cap, with the aux key... only.
