Methods you might find online suggesting otherwise are usually unreliable, dangerous, or simply scams. They often involve manipulating the vehicle's wiring, which carries risks of short circuits and fire.
If you've lost your keys, your only reliable options are:
* Contact a locksmith specializing in automotive security: A reputable locksmith will have the tools and expertise to create a new key or bypass the anti-theft system safely. Be prepared to provide proof of ownership.
* Contact a Jeep dealership: They can program new keys for your vehicle, but this will likely be the most expensive option.
Attempting any other method is strongly discouraged. It's far safer and less expensive in the long run to go through the proper channels to regain access to your vehicle.
