Ignition Lock Cylinder Guide for 1994-2001 Chrysler LHS
Having trouble with a stuck key or a no-start condition? This guide covers what LHS owners need to know before replacing the ignition lock cylinder.
- First, determine if your LHS has a standard key (1994-1997) or a chipped Sentry Key (1999-2001). 1998 owners must verify.
- If you have a Sentry Key, the new keys that come with the cylinder MUST be programmed by a professional, which is an additional cost.
- Replacement is a simple DIY job for most, requiring basic tools and taking less than an hour.
- Aftermarket brands like Standard Ignition and Dorman offer reliable, cost-effective alternatives to expensive OEM parts.
Is Your Ignition Lock Cylinder Failing?
A worn-out ignition lock cylinder in your Chrysler LHS will give you clear warning signs. Because this part can leave you stranded if it fails completely, it's best to address these symptoms early. You may need a new ignition lock cylinder if you experience one or more of the following issues:
- Key is hard to turn: You have to jiggle or force the key to get it to turn to the 'ON' or 'START' position.
- Key is difficult to insert or remove: The key feels sticky, gritty, or gets stuck in the ignition. This is a very common sign of worn internal parts.
- Car won't start: You can turn the key, but the engine doesn't crank. While many other issues can cause a no-start condition, a bad lock cylinder can prevent the ignition switch from getting the signal to start the car.
- Engine stalls while driving: In rare and severe cases, a worn cylinder can lose contact internally, shutting the engine off while you are driving. This is a major safety hazard as it also causes a loss of power steering and brakes.
The Most Important Factor: Chipped vs. Non-Chipped Keys
Before buying a new ignition lock cylinder for your LHS, you must determine if your vehicle has the Sentry Key Immobilizer System (SKIS). This anti-theft system uses a key with a computer chip (transponder) inside. If you use the wrong type of part, your car will not run.
- 1994-1997 Models: These years used a standard, non-transponder metal key. Replacement is straightforward. The new aftermarket lock cylinder will come with a new set of keys. You will then have one key for the ignition and your original key for the doors and trunk.
- 1999-2001 Models: These years came with the Sentry Key system. The key has a gray head and a transponder chip inside that communicates with the vehicle. If you replace the lock cylinder, the new keys must be programmed to the car by a dealer or a locksmith with the correct tools, or the engine will start and then shut off after two seconds.
- 1998 Models: This was a transition year. Owners of a 1998 LHS must verify which system they have. A key with a plain black head is likely a standard key, while a key with a thicker, gray plastic head is a Sentry Key.
Warning for 1999-2001 LHS Owners
Simply installing a new lock cylinder is not enough. The new keys must be professionally programmed to your vehicle's computer. Failure to do so will result in a car that does not run. This will add to the total cost of the repair.
Choosing the Right Aftermarket Brand
For a vehicle like the 1994-2001 LHS, a quality aftermarket part offers a great balance of value and reliability. OEM parts are available but are significantly more expensive. Here's a breakdown of the available aftermarket brands:
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a well-respected brand often used by professional mechanics. Their parts are known for meeting or exceeding original equipment standards, offering excellent fit and long-term reliability.
- Standard Aftermarket (Dorman): Dorman is a popular choice that provides cost-effective solutions. They are known for wide availability and often include helpful components in their kits. Some Dorman kits for other vehicles include tools to "re-key" the new cylinder to match your original key, but this can be a delicate process.
- Economy (Replacement, Skyward): These brands are typically the most affordable. They can be a good choice for a budget-minded repair, but be aware that consistency in fit and material quality may not be on the same level as premium or standard brands.

| New OEM (Mopar) Part | $195 - $310+ |

Frequently Asked Questions
Are there any recalls on the Chrysler LHS ignition lock cylinder?
No. While Chrysler has issued recalls for ignition switches on other models and years, extensive searches of the NHTSA database show no specific recalls for the ignition lock cylinder on the 1994-2001 Chrysler LHS.
Do I need to replace the ignition switch at the same time?
Not necessarily. The ignition lock cylinder is the mechanical part, and the ignition switch is the electrical part it controls. They are separate components. If your symptoms are purely mechanical (key sticking, hard to turn), you likely only need the lock cylinder. If you have electrical issues (dashboard lights flickering, accessories not working), the switch might be the problem.
Can I re-key the new cylinder to use my original key?
Maybe. Some aftermarket kits, particularly from Dorman, may come with the small pins (tumblers) needed to re-key the new cylinder. This is a detailed process that involves disassembling both the old and new cylinders and matching the tumbler sequence. If done incorrectly, 🎬 See how to re-key your new cylinder to match your original key. the lock will not work. For most people, it is simpler to just use the new keys provided with the aftermarket cylinder and have a separate key for the ignition.
What happens if I have a 1999-2001 model and I don't program the new keys?
The car's Sentry Key Immobilizer System will not recognize the new key. The engine will start, run for approximately two seconds, and then stall. The vehicle will be undrivable until the keys are properly programmed.
