Toyota and Scion owners, if you've lost your key fob or need a spare, this Keymall replacement is exactly what you're looking for! This smart prox remote works with several models including Venza (2009-2014), 4Runner (2010-2018), Prius C (2012-2014), Prius V (2012-2016), and Scion tC (2011-2016). The key specs you need to check are FCC ID: HYQ14ACX, Part Number: 89904-47230, and Board Number: 271451-5290 GNE Board. It operates on 314.3MHz frequency and uses a CR2032 battery. The three-button design gives you lock, unlock, and panic alarm functions - everything you need for convenient keyless entry. Now, here's the important part: this is an aftermarket key without logos on the back, and you'll need to get it programmed by a qualified locksmith (dealers often can't program aftermarket keys). It comes complete with battery, chip, circuit board, and an uncut emergency key ready for cutting. Before ordering, double-check that your original key matches these specifications exactly - same shape, buttons, and blade style. The compatibility can be tricky since same year and model vehicles might have different key systems. But once programmed, you'll have a fully functional spare that works just like your original. It's way more affordable than going through the dealership, and having a backup key gives you that peace of mind we all need!
