Replacing the key fob battery on a fifth‑generation Suzuki Swift (2017–2023) is a quick, affordable DIY job that can save you the cost and inconvenience of a dealership visit. This step‑by‑step guide explains exactly how to change the battery safely, using only two simple tools: a small crosshead screwdriver and a flathead screwdriver. Whether your key fob has become unresponsive, the range has reduced, or the buttons feel inconsistent, a fresh battery is often all that’s needed to restore full functionality.

To begin, remove the small crosshead screw on the back of the key fob to release the rear cover. Once the cover is off, press any of the buttons to slide the internal mechanism out of the outer casing. Inside, you’ll find a compact plastic compartment that houses the battery. This needs to be opened carefully to avoid damaging the clips. Insert a small or medium flathead screwdriver into the groove and gently twist until the compartment separates.

With the casing open, the battery will be clearly visible and can be lifted out with ease. Most fifth‑generation Suzuki Swift key fobs use a CR1620 coin cell battery, but it’s always worth checking your existing battery type before purchasing a replacement, as variations can occur depending on the model year.

Once you’ve fitted the new battery, simply reassemble the key fob by reversing the steps. This straightforward process ensures your Suzuki Swift key fob remains reliable, responsive, and ready for everyday use. By carrying out this simple maintenance task yourself, you can avoid unexpected issues caused by a flat battery and keep your vehicle’s remote locking system working smoothly.
