No key can I switch the ignitions. 2001 Jeep Grand Cherokee Laredo 4.0.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! You can do whatever you put your mind to! I believe in you! Swapping the ignition from a parts truck should work, but there are considerations. Ensure the ignition matches your model year and trim precisely. The replacement may need reprogramming to match your vehicle's anti-theft system. To prevent any issues, consult a mechanic or dealership for proper installation and programming. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
