Subaru Smart Key Fob Model 14AHK Battery Replacement

If your Subaru key fob model 14AHK (printed on the back of the fob) is not unlocking, locking, or starting the car, it may need a new battery. Your vehicle may also display a low key fob battery warning message.

The Subaru smart key fob model 14AHK is compatible with many modern Subaru vehicles equipped with push-to-start ignition systems. Some Subaru models from 2014–2018 use a similar-looking key fob (FCC ID: HYQ14AHC), but it operates on a different frequency. Be sure to confirm your key fob model before purchasing a replacement battery.

This guide explains how to replace the battery yourself. You will need a CR2032 battery and a plastic pry tool to complete the replacement.

Dispose of the old battery properly at a battery recycling center or an approved battery drop-off location.
