How to Fix a Key Fob That Got Wet: A Step-by-Step Guide

Dropping your key fob in water is a sinking feeling. It’s a tiny piece of technology responsible for so much, and now it might be fried. But don’t panic just yet! We’ll walk you through how to fix a wet key fob, increasing your chances of a dry (and functional) outcome.

What Happens When a Key Fob Gets Wet?

Before we dive into the solutions, it’s important to understand the enemy. Water and electronics are a terrible combination. When a key fob gets wet, the water can:

Cause a short circuit: Water disrupts the flow of electricity within the fob, potentially damaging its delicate components.
Corrode metal parts: Over time, even small amounts of water can lead to corrosion, affecting the fob’s battery contacts and other metal parts.
Interfere with the signal: Excess moisture inside the fob can weaken the signal it sends to your car.

How to Fix a Wet Key Fob

Here’s a step-by-step guide on how to resuscitate that soggy key fob:

Act Fast: Time is of the essence. The longer the water sits inside, the more damage it can do.
Remove the Battery: Open your key fob as quickly as possible and remove the battery. This is crucial in preventing a short circuit.
Dry the Exterior: Gently pat the key fob dry with a clean, absorbent cloth or paper towel. Avoid using heat, as this can further damage the internal components.
Absorb Internal Moisture: Bury the key fob (and the battery separately) in a bowl of uncooked rice. Rice acts as a desiccant, drawing out moisture from the air and hopefully, your fob. Leave it for at least 24 hours, if not longer.
Test the Key Fob: After the rice treatment, insert the battery back into the key fob and try to unlock your car. If it doesn’t work, the fob may have suffered irreparable damage.

Still Not Working? Don’t Give Up!

If the rice trick didn’t do the trick, there are still options:

Replace the Battery: Sometimes, a new battery is all it takes to revive a seemingly dead key fob.
Contact a Locksmith or Dealership: If all else fails, a professional locksmith or your car dealership can help you program a new key fob.

Preventing Future Water Damage

Prevention is always better than cure. Here are some simple tips to protect your key fob from water damage:

Keep it in a Waterproof Case: Invest in a waterproof case or pouch to shield your key fob from the elements.
Be Mindful of Your Surroundings: Avoid placing your key fob near sinks, bathtubs, or other water sources.
Consider a Spare Key Fob: Accidents happen! Having a spare key fob readily available can save you time, money, and frustration.
