Key fobs are incredibly convenient, allowing you to remotely lock, unlock, and even start your 2020 Jeep Wrangler. However, like any battery-powered device, the key fob’s battery will eventually need replacing. Understanding how to handle this yourself can save you time and potentially money.
One Jeep owner learned this lesson firsthand when their key fob suddenly failed. Imagine being unable to unlock your doors remotely, and even manually opening the door triggers the security system because the system doesn’t recognize the key. This situation highlights the importance of a functioning key fob and, crucially, a backup plan. In their case, a spare key, fortunately located a couple of hours away, saved the day and got their Jeep running again. This experience underscores a valuable point: having a spare key fob is not just a luxury, but a necessity.
But what if the issue isn’t a dead fob, but simply a dead battery? For 2020 Jeep Wranglers, replacing the key fob battery is often a straightforward process you can do at home. While specific steps can vary slightly depending on the exact fob type, generally, it involves carefully opening the key fob casing, typically using a small flathead screwdriver or similar tool. Inside, you’ll find a small watch-style battery, often a CR2032. Note the battery orientation before removing the old one and replace it with a fresh battery of the same type. Ensure the new battery is correctly positioned before carefully snapping the key fob casing back together.
Regularly checking your key fob’s range and responsiveness can give you early warnings of a weakening battery. If you notice the range decreasing or the buttons becoming less responsive, it’s likely time for a battery replacement. Being proactive with key fob battery maintenance can prevent unexpected lockouts and ensure you always have reliable access to your 2020 Jeep Wrangler. And remember, while battery replacement is often simple, having a programmed spare key fob remains a smart safeguard against more significant key fob failures.
