Jeep Comanche Door Lock Kit and Cylinder Guide (1987-1992)
If your key is getting sticky or the door lock is failing, this guide is for you.
- Failing door locks are a very common issue on 30+ year old Comanches due to mechanical wear.
- The problem can be the lock cylinder, but is often a broken clip or seized latch mechanism inside the door.
- Aftermarket kits like those from Standard Ignition are the standard, reliable replacement as OEM parts are unavailable.
- Replacement is a DIY-friendly task for most owners and can prevent you from being locked out of your truck.
Signs of a Failing Door Lock Kit
On a truck as seasoned as the Jeep Comanche, it's not a matter of if, but when, the original door locks will give you trouble. The symptoms are usually straightforward and mechanical. You'll notice the key becomes difficult to insert or turn, especially in cold weather. In other cases, the lock cylinder might spin freely without engaging the lock mechanism at all. A very common issue is that the internal latch mechanism gets gummed up with old grease and dirt, or the connecting rods and clips inside the door break or pop off, preventing the lock from working even if the key cylinder is fine.
Don't Get Locked Out
Many owners report their locks failing suddenly, forcing them to climb through the sliding rear window to get in. It's wise to address a sticky lock before it fails completely.
Choosing an Aftermarket Door Lock Kit
Original Mopar door lock parts for the 1987-1992 Comanche are long discontinued. This makes the aftermarket the only practical source for new replacements. Fortunately, for a simple mechanical part like this, aftermarket quality is generally very reliable.
Brand Spotlight: Standard Ignition
Standard Ignition (also known as Standard Motor Products or SMP) is a well-regarded brand in the aftermarket world. They are known for producing quality replacement parts that meet or exceed original specifications. Their door lock kits are typically made with durable materials like die-cast zinc cores and brass tumblers, designed to provide a long service life. For a part like a door lock cylinder on a classic Jeep, Standard Ignition is a trusted, go-to choice.

Pro Tip: Check Your Linkages First
Before ordering a new lock kit, it's worth taking off the door panel to inspect the lock mechanism. Sometimes the problem is just a cheap plastic clip that has broken or a rod that has popped out of place. These small parts are often available separately and can be a very inexpensive fix.
Frequently Asked Questions
Will my original key work with the new lock kit?
No. A new door lock kit comes with a new, unique set of keys. The lock cylinders are internally matched to these new keys. For the 1987-1992 Comanche, it was common to have a separate key for the ignition and the doors, so this will likely not change your routine.
Can I replace just one door lock?
Yes, but kits are typically sold with a pair of lock cylinders. Replacing both at the same time ensures both doors work with the same new key, which is more convenient.
Is this a difficult part to replace myself?
For most DIYers, this is a manageable job. It requires removing the interior door panel and carefully detaching a few clips and rods to access the lock cylinder. The cylinder itself is usually held in by a simple clip. The most common frustration is working in the tight space inside the door. The job typically takes about an hour per door.
Are there any recalls for the door locks on the 1987-1992 Jeep Comanche?
No, there are no safety recalls issued by the NHTSA for failures of the door lock cylinders or mechanisms on the 1987-1992 Jeep Comanche.
