So your Lexus key fob is looking pretty beat up after years of use? These replacement shells are exactly what you need to make it look brand new again. The best part - no programming required! You just carefully transfer your existing circuit board and key blade from your old worn-out case into this fresh new shell. It fits a ton of Lexus models including ES, GS, GX, IS, LS, LX, RX, and SC series from various years. The two-pack means you've got a backup or can fix multiple remotes. The installation is pretty straightforward - just make sure your original fob matches the pictures in the listing before ordering. Don't worry about cutting your key blade either, it transfers right over from your old case. If you run into any issues during the swap, their customer service is actually really responsive and will help you out within 24 hours. Seriously, this is way cheaper than buying a whole new key fob from the dealership, and the result looks just as good.
