Lost your Acura key fob or dealing with one that's seen better days? This A-tnewb replacement is exactly what you need to get back to convenient keyless entry! This 4-button remote is a direct replacement for OEM part A2C32523200 and works with Acura MDX models from 2014-2020 and RDX from 2016-2018. Before you order, just check the FCC ID on your original remote - it should be KR5V1X and 314MHz frequency to ensure compatibility. The fob comes pre-loaded with batteries and all the electronic components ready for programming at your dealership or a qualified locksmith. It even includes an uncut emergency key blade that you can get cut to manually unlock doors or start your vehicle if the battery dies. The buttons give you all the standard functions - lock, unlock, panic alarm, and trunk release. Having a working remote means no more fumbling with keys when your hands are full, better security since you can actually lock your doors remotely, and that handy panic button to find your car in crowded parking lots. The build quality feels solid and durable, comparable to the original equipment. They test each unit before shipping and offer a one-year unlimited mileage guarantee for peace of mind. Just remember - this needs to be programmed to your specific vehicle, so factor that into your plans. For the price compared to dealership replacements, this is an absolute steal that gets you back to convenient, modern car access without the crazy markup!
