Pinning this so I have it if I ever need it again. The remotes for my cobalt weren't working to lock the doors or use the remote start. They would unlock the doors and open the trunk without a problem, so I knew the batteries were fine. I ordered two of these, put them in within 2 minutes, and both remotes work like new. Awesome and inexpensive fix. I could order 10 of these for the price of one new remote from Chev.
