An ignition that fights you is one of the most frustrating car problems there is. The key goes in but won't turn, the steering wheel feels locked solid, the key sticks in the cylinder, or the car only starts after jiggling the key just right. Those symptoms usually point to a worn ignition cylinder, a damaged or worn key, or a steering column lock that has bound up. They tend to get worse over time, and a car that starts today can strand you in a parking lot tomorrow.

In Simi Valley, being stranded is a real inconvenience. The city is spread out along the SR-118 corridor, with commuters heading toward the SR-23 and the Los Angeles basin, and plenty of daily driving between neighborhoods, schools, and shopping. Most households here rely on a car for nearly everything, so an ignition problem quickly becomes a problem for the whole day.

Crenshaw Lock Company is fully mobile. There is no shop to tow your car to. We come to your driveway, workplace, or parking space and diagnose the problem on site. Owner and lead technician David Shar has been serving Greater Los Angeles and Ventura County since 1987, and we are available around the clock. Sometimes the fix is as simple as a new key or cleaning a worn cylinder; other times the cylinder needs replacing and the key needs to be cut or programmed to match. We will explain which it is before work begins.

How it works in Simi Valley

  1. 1

    Call and describe the symptoms

    Call (323) 997-8867 and tell us the make, model, and year, and what the ignition is doing. Does the key refuse to turn, stick, spin freely, or start the car only some of the time? Those details help us arrive with the right tools and parts in mind.

  2. 2

    Check the key and steering lock first

    Many 'bad ignition' calls start with a worn key or a steering column lock under tension. We inspect the key for wear, then see whether gently relieving the steering wheel pressure lets the key turn. Ruling out simple causes can save you a replacement.

  3. 3

    Diagnose the cylinder

    If the key is fine, we examine the ignition cylinder for worn wafers, debris, or damage from a previous attempted theft. We determine whether it can be repaired or needs replacing, and we tell you which before proceeding.

  4. 4

    Repair or replace the cylinder

    Where possible we service the existing cylinder. When it's too worn, we replace it and set it up so your key works with the new part. We work to avoid unnecessary damage to the steering column and dash.

  5. 5

    Cut or program keys as needed

    Many modern vehicles use transponder keys that must communicate with the car. After the repair, we make sure the key you'll be carrying actually starts the vehicle and that spare keys work as well.

  6. 6

    Test and hand back

    Before we finish, we test the ignition repeatedly: turning, starting, and removing the key, plus the steering lock. You leave knowing what failed, what was done, and what to watch for.

What affects the price

  • Whether the existing cylinder can be repaired or must be fully replaced, since replacement involves more parts and labor.
  • Your vehicle's make, model, and year, which determine the cylinder design and how difficult the column is to work around.
  • Whether the key is a basic mechanical key or a transponder or smart key that requires programming to the vehicle.
  • How many keys need to be cut or programmed, including spares if the originals are worn or lost.
  • The condition of the steering column and any damage from a previous theft attempt or forced key.
  • The time of day and location, since we're available 24/7 and travel to you throughout Simi Valley.

Ignition Repair across Simi Valley

Simi Valley drivers park in a wide mix of places, and ignition trouble shows up in all of them. In Wood Ranch and Big Sky, it's often a car in a garage or a driveway on a quiet street when the key suddenly won't turn before the morning commute. In the Texas Tract and Bridle Path, we often see older vehicles that have been driven for years on worn keys, which is a classic cause of sticking cylinders. In Santa Susana Knolls, winding lanes and tight parking mean a mobile technician who comes to you is far more practical than arranging a tow.

We also help people stuck away from home. A key that won't turn in the lot at the Simi Valley Town Center, near the Ronald Reagan Presidential Library & Museum, or after a walk at Rancho Simi Community Park or Corriganville Park is a different kind of problem than one in your own driveway, and we come to wherever you are. Whether you're in 93063, 93065, 93062, 93064, or 93094, one call to (323) 997-8867 reaches us.

Because we're mobile, we can work along the roads you actually drive, from Madera Rd and Tapo Canyon Rd to Cochran St, First St, Sycamore Dr, and the SR-118. If your car is stuck at a business along Cochran or at a park near Santa Susana Pass, tell us the location and we'll head your way.

Ignition Repair in Simi Valley — FAQs

Why won't my key turn in the ignition?
Common causes include a worn key, a worn ignition cylinder, debris inside the cylinder, or a steering column lock under tension. We check the simple causes first and then diagnose the cylinder. Call (323) 997-8867 and describe what's happening.
Can you come to me in Simi Valley, or do I need to tow the car?
We're fully mobile, so you don't need a tow. We come to your home, workplace, or wherever the car is parked in Simi Valley and do the diagnosis and repair on site.
Do you offer ignition repair at night or on weekends?
Yes. We're available 24/7, including nights, weekends, and holidays. Call (323) 997-8867 any time you're stuck.
Do I need a new ignition cylinder, or can it be repaired?
It depends on the wear and damage. Some cylinders can be serviced; others are too worn to trust. We inspect first and tell you which applies before doing any work.
Will the new ignition work with my existing key?
Usually we set up the replacement so it works with your key, or we cut a new key to match. If your key is badly worn, we may recommend replacing it as well, since a worn key can damage a new cylinder.
My car has a transponder key. Can you handle that?
Yes. Many modern vehicles require the key to be programmed to the car. After the repair, we make sure the key actually starts the vehicle and test any spares.
My steering wheel is locked and the key won't move. What should I do?
Try gently turning the wheel back and forth while turning the key, but don't force it, since that can snap the key or damage the cylinder. If it still won't budge, call (323) 997-8867 and we'll come help.
How is the price determined?
It depends on whether the cylinder is repaired or replaced, your vehicle, the type of key, how many keys are needed, and any damage to the column. We explain the factors and the plan before we start.
