Guide overview

Before you begin

If your 2018 Jeep Wrangler key FOB only works intermittently, this can cause a problem as the Jeep Wrangler is a push-button start car.

Be careful with the internal battery as it could be corroded and needs to be disposed of properly. This guide is simple and can be done quickly instead of paying a high price for a replacement key.
