Experiencing issues with your 2010 Chevy HHR key fob? Before you rush to the dealership and spend a significant amount on a replacement and programming, you might be able to fix it yourself with a simple trick. Many Chevy HHR owners encounter problems with their key fobs, often assuming they need professional programming or a brand new device. However, the solution could be much simpler and cost-effective than you think. This guide will walk you through a common issue and a straightforward DIY repair that might just save you time and money.
The Common Culprit: Battery Contact Corrosion
Often, the reason your 2010 Chevy HHR key fob stops working isn’t due to programming issues at all. A very frequent problem is corrosion buildup on the battery contacts inside the fob. This corrosion can impede the flow of power from the battery, making it seem like your key fob is dead or needs reprogramming. The good news is, this is usually an easy fix you can do at home with minimal tools and no special expertise required. You might not even see the corrosion with the naked eye, which is why this simple cleaning step is often overlooked.
Step-by-Step Guide to Cleaning Your Key Fob Contacts
Before assuming you need to program a new key fob for your 2010 Chevy HHR, try this simple cleaning method. It could resolve the issue and get your key fob working again in minutes.
- Open the Key Fob: Carefully pry open your Chevy HHR key fob. A dull knife or a similar tool can be used to gently separate the two halves. Don’t worry too much about being gentle; these fobs are designed to be opened, and a little pressure is okay. You’ll notice a waterproof seal around the edge.
- Remove the Battery: Once open, remove the battery. Most likely, it’s a CR2032 battery. Consider replacing it with a new one to rule out a dead battery as the problem. These batteries are readily available at most stores for just a few dollars.
- Clean the Contacts: Take a 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 areas: two prongs and a base. The base contact is often where corrosion builds up most.
- Dry the Contacts: Use the clean, dry end of the Q-tip to thoroughly dry all the contact points you just cleaned with lemon juice. Ensure no moisture remains.
- Replace the Battery and Test: Insert the battery back into the key fob and carefully snap the fob back together. Now, test your key fob with your 2010 Chevy HHR to see if it’s working again.
Beyond Corrosion: Other Potential Key Fob Issues
While battery contact corrosion is a very common problem, there are other reasons your 2010 Chevy HHR key fob might not be functioning correctly. Another issue that sometimes occurs is that one of the small prongs inside the fob can become unsoldered. If cleaning the contacts doesn’t work, this could be the problem.
If you suspect a soldering issue, consider visiting a battery specialty store like Batteries Plus or Interstate Batteries. They often offer free key fob inspections and might be able to quickly resolder a loose prong for a minimal charge, or even for free. This is still a much cheaper option than purchasing a new key fob and paying for programming at a dealership.

Before spending money on a new key fob and programming for your 2010 Chevy HHR, take a few minutes to try cleaning the battery contacts. It’s a simple, free, and often effective solution.
