Please try
changing again a battery in your car remote. This
usually helps. You can purchase a new or used car remote from our website - http://www.carandtruckremotes.com/index.html
We offer free shipping for batteries.
If you changed
the battery and your Chevrolet impala keyless
entry remote still does not work, most likely you need a new remote. You
can purchase a brand new or used good condition (B-stock) remote on our
website. All remotes come with a 90 day money back policy. Please click on this
