Dealing with a malfunctioning key fob can be a major headache, especially when dealerships often quote exorbitant prices for a replacement. If you own a 2006 Chevrolet HHR and your key fob has stopped working reliably, don’t rush to spend hundreds of dollars just yet. There’s a simple, often overlooked fix that could save you a significant amount of money and frustration. Before you consider buying a new key fob or paying for programming, try this easy DIY solution that addresses a common issue: battery contact corrosion.
Many times, the problem isn’t a broken key fob, but rather a build-up of corrosion on the battery contacts inside. This corrosion can interrupt the flow of power, preventing your key fob from communicating with your vehicle. The good news is, this is often a quick and easy fix you can do yourself with just a few household items.
Step-by-Step Guide to Cleaning Your 2006 HHR Key Fob Contacts
Before you assume you need a new key fob, follow these steps to clean the battery contacts and potentially restore your key fob to perfect working order:
-
Open the Key Fob: The 2006 Chevrolet Hhr Key Fob is designed to be opened. Carefully use a dull knife or a similar tool to pry it open. You’ll notice a waterproof seal around the edge, so it might require a bit of gentle prying. Don’t worry about breaking it – you’re already potentially facing a non-functional fob.
-
Remove the Battery: Once open, remove the battery. It’s a good idea to replace it with a new CR2032 battery. These batteries are widely available and inexpensive, usually costing around $3-$4. Replacing the battery eliminates a dead battery as a possible cause of the problem. You can find CR2032 batteries at most drug stores, supermarkets, and certainly at battery specialty stores like Batteries Plus or Interstate Batteries.
-
Clean the Battery Contacts: Take a cotton swab (Q-tip) and apply a small amount of lemon juice to one end. Gently wipe all the battery contact points inside the key fob. There are typically three contact points: two small prongs and a larger base contact. Corrosion is most often found on the base contact. The mild acid in lemon juice helps to dissolve the corrosion.
-
Dry the Contacts: Use the clean, dry end of the cotton swab to thoroughly dry all the contact points you just cleaned. Ensure there is no moisture remaining.
-
Replace the Battery and Reassemble: Install the new CR2032 battery and carefully snap the key fob back together until it is securely closed.
-
Test Your Key Fob: Go to your 2006 Chevrolet HHR and test the key fob functions. If battery corrosion was the issue, your key fob should now be working perfectly!

Other Potential Issues and Professional Help
While battery contact corrosion is a frequent culprit for key fob problems, there are other possibilities. Another common issue, particularly in HHR key fobs, is a broken solder joint on one of the prongs inside the fob. If cleaning the contacts doesn’t solve the problem, this could be the issue.
If you suspect a soldering problem, or if you’re uncomfortable opening the key fob yourself, consider visiting a battery specialty store like Batteries Plus. They often offer free key fob inspections and may be able to quickly resolder a loose connection for a minimal charge, or even for free. This is a far more affordable option than purchasing a new key fob from a dealership.
Final Thoughts
Before spending a significant amount of money on a new key fob for your 2006 Chevrolet HHR, try this simple cleaning method. It’s a quick, easy, and cost-effective solution that resolves a surprisingly common problem. You might be amazed at how easily you can restore your key fob’s functionality and save yourself a trip to the dealership and a hefty bill.
