Lost or broken your Cadillac key fob? No worries—this Boxonly replacement remote is here to save the day. It's designed specifically for the 2015, 2016, 2017, 2018, 2019, and 2020 Cadillac Escalade ESV models (make sure your vehicle has push-to-start, okay?). This is a non-OEM accessory, but it works just like the original. It's got 6 buttons: lock, unlock, remote start, panic, trunk open, and trunk close. The frequency is 315MHz, and the FCC ID is HYQ2AB (check your old fob to match this before buying!). It comes with a battery installed, so it's ready to go—but heads up, you WILL need to get it programmed and cut by a qualified locksmith or dealership. Don't try to DIY this part; it won't work. Also, make sure your original key has the same button layout before purchasing. The build quality is solid, with a plastic and metal housing that feels sturdy in hand. Once programmed, it should respond quickly and reliably. Just remember: get it programmed BEFORE cutting the key, otherwise you might end up with a useless key. Package includes one remote with battery. A handy and affordable solution to get back your keyless entry convenience!
