If your car remote has taken an unexpected swim, don’t panic! Getting your car remote wet can be a frustrating experience, leaving you stranded and wondering How To Fix A Car Remote That Got Wet. This article provides a comprehensive guide to rescuing your soaked key fob and getting back on the road. We’ll cover everything from immediate actions to advanced troubleshooting, ensuring you’re equipped to handle this common automotive issue.

First Aid for Your Waterlogged Car Remote

Time is of the essence when dealing with a wet car remote. The quicker you act, the better your chances of reviving it. First, remove the remote from the water source immediately. Next, try to shake out any excess water. This simple step can prevent further damage to the internal components.

1. Remove the Battery: This is crucial! Water and electricity don’t mix. Carefully pry open the remote casing and take out the battery. If your remote uses a coin cell battery, you might need a small screwdriver.
2. Dry the Components: Use a soft, absorbent cloth to gently pat dry all the parts of the remote, including the battery compartment. Avoid using a hairdryer, as the heat can damage the delicate electronics. A vacuum cleaner with a hose attachment can also be useful for sucking out moisture from hard-to-reach areas.
3. Isopropyl Alcohol Bath (Optional): For stubborn moisture, consider submerging the remote’s circuit board in isopropyl alcohol (90% or higher). This helps displace water and evaporate quickly, reducing the risk of corrosion. Let it air dry completely before reassembling.

How to Fix a Car Remote That Got Wet: Advanced Troubleshooting

Sometimes, simple drying isn’t enough. If your car remote still isn’t working after the initial steps, try these advanced troubleshooting methods.

Checking for Corrosion

Corrosion can be a silent killer for electronics. Examine the battery contacts and the circuit board for any signs of corrosion (a greenish-white buildup). If you spot any, carefully clean it off with a small brush or cotton swab dipped in isopropyl alcohol.

Testing the Battery

Even if the battery looks fine, it might have been damaged by the water. Test it with a multimeter or try a new battery. A weak battery can cause intermittent issues or prevent the remote from working altogether.

Reprogramming the Remote

In some cases, getting wet can disrupt the programming of your car remote. Consult your car’s owner’s manual or contact your dealership for instructions on how to reprogram the remote. This usually involves a specific sequence of button presses or using the car’s ignition.

Preventing Future Water Damage

Prevention is always better than cure. Here are some tips to protect your car remote from future water damage:

• Waterproof Case: Consider investing in a waterproof case or pouch for your car remote. This provides an extra layer of protection against accidental splashes or even full submersion.
• Keep it Dry: Avoid leaving your remote in damp places, such as pockets or bags that might get wet.
• Regular Maintenance: Periodically clean your car remote with a slightly damp cloth to remove dirt and grime, which can trap moisture and accelerate corrosion.

Still Having Trouble?

Sometimes, even the most diligent efforts can’t revive a waterlogged car remote. If you’ve tried all the troubleshooting steps and your remote still isn’t working, it might be time for a replacement. You can usually purchase a new remote from your car dealership or online.
