Review on VOFONO Key Fob Keyless Entry Remote Set of 2 for Toyota Avalon, Solara, Sequoia, Highlander (GQ43VT20T 4-Btn): 2005-2008 Avalon, 2004-2008 Solara, 2008-2017 Sequoia, 2008-2013 Highlander by Fock Dean

One of these devices didn't work when I received it - no transmission (and no battery problem). Not only is there no replacement support (and the seller isn't responsive), but they cost $100-$150 to program. Even if you end up having to order one from a different retailer, you'll end up paying double for programming (if a technician would only charge you once to program both fobs). So order from another seller and make sure both devices work before paying for programming!
