Discovering your car key fob has survived a full cycle in the washing machine and dryer can be a moment of panic. It’s a common mishap, and thankfully, not always a disaster. As automotive repair experts at keyfobprog.com, we’re here to guide you through the steps to assess and potentially revive your waterlogged key fob. Contrary to initial fears, water itself isn’t the primary enemy of electronics. The real culprits are the contaminants in the water, corrosive substances, and the damage that can occur if moisture is trapped inside. Let’s break down what you need to do to address this situation and get your key fob working again.
Immediate Actions After the Wash Cycle
Once you realize your key fob has been through the washer and dryer, quick action is crucial. The first and most important step is to remove the battery immediately. This prevents any potential short circuits or further corrosion caused by residual water interacting with the battery terminals.

Avoid the temptation to test the key fob right away. Do not press any buttons. Activating the fob while it’s wet can exacerbate any existing issues and potentially cause more damage. Instead, focus on gently disassembling the key fob if you’re comfortable doing so. This will allow for a more thorough drying process. If you’re unsure how to open your key fob, consult your owner’s manual or search online for specific instructions for your car model.
Drying Your Waterlogged Key Fob: Patience is Key
The next critical step is to thoroughly dry your key fob. The goal here is to remove all traces of moisture, preventing corrosion and ensuring proper function. Here are some effective drying methods:
- Air Drying: This is the gentlest and often most effective method. Leave the disassembled key fob components in a warm, dry place with good air circulation. Avoid direct sunlight or excessive heat, as this could damage sensitive components. Allow ample time for drying – at least 24 to 48 hours is recommended.
- Rice Bath: Placing the key fob in a bowl of uncooked rice is a common home remedy for drying electronics. Rice acts as a desiccant, absorbing moisture. Bury the key fob completely in the rice and leave it for at least 24 hours.
- Silica Gel Packets: If you have silica gel packets (those small packets found in shoe boxes or electronics packaging), these are excellent for absorbing moisture. Place the key fob and several silica gel packets in a sealed container for 24 to 48 hours.
Avoid using a hairdryer or oven to speed up the drying process. Excessive heat can damage the delicate electronic components within the key fob, potentially causing irreversible damage.
Cleaning Battery Contacts and Internal Components
Even if the water was relatively clean, it can still leave behind mineral deposits or carry dirt into the key fob’s switches and contacts. Once the key fob is thoroughly dry, inspect the battery contacts for any signs of corrosion.
- Pencil Eraser Cleaning: A simple and effective way to clean corroded battery contacts is to gently rub them with a pencil eraser. This can remove light corrosion and improve electrical conductivity. Do the same for the battery terminals themselves.
- Isopropyl Alcohol (Optional): For more stubborn dirt or residue, you can use a cotton swab lightly dampened with isopropyl alcohol (90% or higher). Gently clean the contacts and any accessible internal components. Ensure the alcohol evaporates completely before reassembling the key fob.
Potential Issues and When to Seek Professional Help
After drying and cleaning, reassemble your key fob and insert a fresh battery. Test its functionality. In many cases, these steps will be enough to revive your key fob. However, some issues may require professional attention:
- Corrosion Damage: If you notice significant corrosion on the circuit board or other internal components, the damage might be too extensive for a simple DIY fix.
- Switch Malfunction: If the buttons on your key fob are no longer working or are erratic after drying, the switches themselves might have been damaged by dirt or water.
- Circuit Board Issues: In more severe cases, water damage could affect the key fob’s circuit board, leading to complete failure.
If your key fob still doesn’t work after attempting these troubleshooting steps, it’s best to consult a professional. At keyfobprog.com, or your local automotive locksmith or dealership, can diagnose the problem and offer solutions, which may include reprogramming or replacement.
Prevention: Avoiding Future Washer and Dryer Incidents
While it’s reassuring to know that a key fob can sometimes survive a wash cycle, prevention is always better than cure. Here are a few tips to help avoid this mishap in the future:
- Check Pockets: Make it a habit to check your pockets before doing laundry.
- Designated Key Spot: Establish a designated place to keep your keys when you’re at home, ensuring they are not left in pockets that might end up in the wash.
- Key Fob Case: Consider using a protective case for your key fob. While not entirely waterproof, it can offer some protection against accidental splashes and spills.
By acting quickly, drying thoroughly, and taking preventative measures, you can minimize the impact of a key fob’s unexpected journey through the washer and dryer and keep your car keys functioning reliably.
