Review on Lexus Key Shell Replacement: Unlock Your Vehicle with Ease Using Your Original Key and Chip – No Locksmith Needed! by Roy Bush

I've bought 4 of these over the last few years. 2 held up great, but 2 where I had to change the batteries didn't. It looks like when the case is disassembled the screws don't tighten as they used to, leaving the metal key loose if there is a non-tightening one or two on the side of the key! Unfortunately I had to buy another one! Still the cheapest solution I've found, just wish they had lasted longer. No problem until you take them apart to replace the batteries. Also, the seller didn't mention that they work on 1998-2007 Toyota Landcruiser key fobs!
