What you need to know before you start

Replacing the ignition lock cylinder on a 2000 Jeep Wrangler is a job you can do yourself with basic tools, though it requires removing the steering column cover and working in a tight space. The cylinder itself costs between $30 and $80 depending on whether you buy OEM (original equipment manufacturer) or aftermarket, and the whole job takes one to two hours. You will need your vehicle identification number (VIN) when ordering the replacement, because the new cylinder must be keyed to match your existing key.

The main decision is whether to do this yourself or have a dealer or locksmith handle it. A dealer will charge $150 to $300 in labor plus the part cost. A locksmith may charge $100 to $200. If you are comfortable working with small fasteners and following a sequence of steps, the DIY route saves money and gives you control over timing.

Key Takeaways

  • You will need to remove the steering column cover and the ignition switch assembly to access the lock cylinder, which requires a screwdriver and possibly a small punch or Allen wrench.
  • The new cylinder must be keyed to your existing key, so order it with your VIN or have a locksmith rekey it before installation.
  • The cylinder is held in place by a small retaining pin that you remove by turning the key to the "On" position and pushing the pin out from underneath the column.
  • Once the old cylinder is out, the new one slides in and the retaining pin goes back in to lock it in place.
  • After installation, test the key in all positions (Off, Accessory, On, Start) before reassembling the column cover.

Gather your tools and parts

Before you start, collect a screwdriver set (Phillips and flathead), a small punch or Allen wrench (usually 3/32 inch), and a flashlight or headlamp. You may also need a steering wheel puller if the wheel is in your way, though on most 2000 Wranglers you can work around it by turning the wheel fully to one side.

Order the replacement ignition lock cylinder ahead of time. Call a Jeep dealer with your VIN and ask for the cylinder for a 2000 Wrangler, or order online from a parts supplier like RockAuto or Amazon. The part number varies slightly depending on whether your Wrangler is a TJ model (1997–2006), but all 2000 models use the same cylinder. When the part arrives, verify that it comes keyed to your existing key, or plan to have a locksmith rekey it (usually $15 to $30).

Remove the steering column cover

Sit in the driver's seat and locate the screws holding the steering column cover in place. On a 2000 Wrangler, there are typically three to four screws: two on the underside of the column (you will need to reach up under the dash), one or two on the sides, and sometimes one at the top near the steering wheel. Use a Phillips screwdriver to remove them.

Once the screws are out, gently pull the cover away from the column. It may be tight; wiggle it side to side rather than yanking straight out. You do not need to remove the cover completely — you just need enough space to see and access the ignition cylinder and the retaining pin underneath.

Locate and remove the retaining pin

With the cover pulled back, you will see the ignition cylinder sticking out from the column. Underneath it, there is a small metal pin (called the retaining pin or lock pin) that holds the cylinder in place. To remove it, insert your key into the cylinder and turn it to the "On" position — this aligns a small hole in the cylinder with the pin.

Once the key is in the "On" position, use your small punch or Allen wrench to push the retaining pin out from underneath the column. It will slide out toward you. Keep it somewhere safe; you will reuse it with the new cylinder. If the pin is stuck, do not force it — spray a small amount of penetrating oil (like WD-40) around the pin, wait a few minutes, and try again.

Pull out the old cylinder and install the new one

With the retaining pin removed, turn the key back to the "Off" position and pull the cylinder straight out of the column. It should slide out easily. If it does not, check that the retaining pin is fully out and that nothing else is holding it.

Take the new cylinder and insert it into the same opening, making sure it goes in straight and all the way. Turn your key to the "On" position again to align the hole, then slide the retaining pin back in from underneath. You should hear or feel a small click as it seats. Turn the key back to "Off" to lock the pin in place.

Test the new cylinder before reassembling

Before you put the steering column cover back on, test the new cylinder in all four positions: "Off," "Accessory," "On," and "Start." The key should turn smoothly in each position and return to center when you release it from "Start." If the key is hard to turn, does not return properly, or does not fit at all, stop and contact the parts supplier or a locksmith — the cylinder may not be keyed correctly to your key.

Once you confirm everything works, slide the steering column cover back into place and reinstall the screws. Tighten them firmly but do not over-tighten, as the plastic can crack.

When to call a professional instead

If the retaining pin will not budge even after penetrating oil, or if the new cylinder does not fit into the opening, stop and take the Wrangler to a dealer or locksmith. Forcing a stuck pin can break it or damage the column, and a mismatched cylinder can indicate an ordering error that needs to be corrected before installation.

If your key is broken or lost, a locksmith can rekey the new cylinder to a key you provide, or create a new key from scratch. This adds $20 to $50 to the cost but ensures the cylinder works with your existing locks.

Frequently Asked Questions

Do I need to remove the steering wheel to do this job?

No. On a 2000 Wrangler, you can access the ignition cylinder by straightforward turning the wheel fully to one side and removing the column cover. A steering wheel puller is only necessary if the wheel is in your way and you cannot reach the fasteners or the cylinder itself.

What if the new cylinder does not match my key?

Contact the parts supplier and explain the mismatch. Most will exchange it for a cylinder keyed to your VIN. If you ordered from a dealer, they will rekey it at no charge. A locksmith can also rekey any cylinder for $15 to $30.

Can I reuse the old retaining pin with the new cylinder?

Yes. The retaining pin is generic and works with any ignition cylinder on a 2000 Wrangler. Keep it safe during removal and reinstall it with the new cylinder.

How long does this job actually take?

One to two hours for someone doing it for the first time. The longest part is usually locating and removing the retaining pin. If you have done it before, you can finish in 30 to 45 minutes.

What if my Wrangler has a steering column lock?

Some 2000 Wranglers have a steering column lock that engages when the ignition is off. This does not affect the cylinder replacement — you will still access it the same way. The lock itself is separate and does not need to be removed.
