How to Fix the 'Damaged Key' Error on a 2011 Jeep Cherokee Laredo?

If you're encountering a "damaged key" error on your 2011 Jeep Cherokee Laredo, it's essential to start by checking the key fob batteries. Even if the fobs can lock and unlock the doors, that doesn't necessarily mean the batteries are functioning well enough to start the engine. If you haven't replaced the batteries since you bought the vehicle, it's a good idea to do so. The key fob uses a CR 2032 battery, which is relatively easy to find and replace. If replacing the batteries doesn't resolve the issue, the next step is to consider the ignition module. It's quite unusual for both key fobs to fail simultaneously, but it's important to eliminate the simplest possibilities first. Additionally, there is a Technical Service Bulletin (TSB) related to this issue, as it's a common problem for this model. It might be worth contacting your dealership to inquire about the TSB regarding the "damaged key" error. If the new batteries don’t fix the problem, you may need to take your vehicle to the dealership for reprogramming of the keys. Sometimes, a reset can also help; you can try disconnecting both battery cables from the terminals for about two minutes before reconnecting them. This can sometimes clear up electronic glitches. After doing this, test the key fob again to see if the issue persists.
