Review on High-Quality Keyless Entry Remotes for Toyota Camry 2007-2010 - Set of 2 by Andy Thorson

No Cancer! These keys will work if you take Techstream a few times (sensitive to interference) and cut them with an automatic cutter available at Lowe's or Home Storage. Since it has a double cut, there is a high chance of error when using a hand cutter. There are also automatic cutting machines that accept 5-digit codes printed on the car's door cylinder. I haven't tried cloning, which ALL hardware stores do, but I programmed it with techstream. Cloning and programming a master key are two different things. They work with Techstream, hardware store cloning is unknown.
