Using adhesive lined heat shrink. For example, this particular car was a 18 camary all keys lost. oem flip key. The user cloned super chip from a new H key. Generated remote. Use IM608 to learn key then remote. All working good.
Super glue works just fine too. But sometimes will stuck cap etc messy and many times have to open a new tube for every Job. Gets annoying and messy.
I use hot glue, and position it into the tip of the flip key. Some of the remotes have a small LED you might be covering.
3). some use silicone
I use glue stick for glue guns but just use my lighter to melt the glue. No need a glue gun or wait time to warm up etc. takes literally 10secs to drop some glue on it and done.
just buy super remotes they have built in super chip.
NOTE: XHorse makes several versions of Toyota look alike keys, but they don’t have chips. It’s not like the Ford style where you get to choose with or without chip.
