An ignition that sticks, a key that refuses to turn, or a steering column that stays locked can strand you at the worst moment. In Walnut, where most households depend on a car for the SR-60 commute, the run up Grand Ave to campus, or errands along Valley Blvd and Lemon Ave, a failing ignition is more than an annoyance. It can leave you stuck in a driveway in Walnut Heights or a parking lot near Mt. San Antonio College.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades working on automotive locks and ignitions. We are fully mobile and available 24/7. There is no storefront to visit; we bring the tools and expertise to wherever the vehicle is parked.

Ignition trouble usually has a cause you can identify: a worn key, a damaged cylinder, a stuck steering lock, or debris built up over years of use. Often the problem can be fixed on site by repairing or replacing the cylinder, rather than a costly tow to a dealership. Here is how we approach it, and what affects the cost.

How it works in Walnut

  1. 1

    Call and describe the symptoms

    Call (323) 997-8867 and tell us what the car is doing. Does the key go in but not turn? Does it turn but not start the engine? Is the key hard to remove? Those details help us bring the right parts and tools.

  2. 2

    We come to your vehicle

    We are fully mobile, so we meet you where the car sits, whether that is a driveway in Walnut, a lot near campus, or the shoulder near an SR-60 on-ramp. We confirm the vehicle and your ownership before starting work.

  3. 3

    Diagnose the real problem

    A key that won't turn is not always a bad cylinder. We check the key for wear, test for a stuck steering lock, look for debris, and rule out issues outside the ignition. This keeps you from paying for a part you don't need.

  4. 4

    Repair or replace the cylinder

    If the problem is minor, we may be able to free or service the cylinder. If it is worn or damaged, we replace it and cut keys to match. The right choice depends on your vehicle and the condition of the parts.

  5. 5

    Test and hand over keys

    We test the ignition thoroughly, including starting the engine, turning the key through every position, and removing it smoothly. You get working keys and a clear explanation of what was wrong.

  • Time of day and the location of the vehicle, since we serve you around the clock

Ignition Repair across Walnut

Walnut sits between the San Jose Hills and Puente Hills, and its residents often drive long distances for work, school, and errands. Whether you live in the gated Snow Creek community, in Walnut Heights, or near the Mt. San Antonio College area, ignition trouble tends to show up at inconvenient times: before an early commute, after a late class, or on a family outing to Suzanne Park or Creekside Park.

We serve Walnut ZIP codes including 91789 and 91788. In a gated community like Snow Creek, we can work in your driveway or garage. Near Mt. SAC, we can meet students and staff in campus lots or along Grand Ave. If your car stalls out near SR-57, SR-60, Amar Rd, Nogales St, or Pierre Rd, we can come to you there too.

Walnut's many 1970s-80s and newer households often have more than one vehicle, including older cars handed down to teens and newer models with transponder keys. We work with both. Call (323) 997-8867 any hour, and we will come to you.

Ignition Repair in Walnut — FAQs

Why won't my key turn in the ignition?
Common causes include a worn key, a damaged or dirty cylinder, or a steering wheel lock that is binding. Try gently wiggling the steering wheel while turning the key. If that doesn't help, call (323) 997-8867 and we can diagnose it.
Do you repair ignitions at my home in Walnut?
Yes. We are fully mobile and work at your home, workplace, or wherever the car is parked, including Snow Creek, Walnut Heights, and the area around Mt. SAC.
Can you fix an ignition without towing the car?
In most cases, yes. Because we come to you, many ignition repairs and cylinder replacements can be done on site. Call (323) 997-8867 to describe the problem.
Will you need to replace my whole ignition?
Not always. We diagnose first. Sometimes the cylinder can be repaired or the real issue is a worn key. If replacement is needed, we explain why before proceeding.
Can you make a new key if mine is worn out?
Often yes. A worn key is a frequent cause of ignition trouble, and we can cut a new one, and program it if your vehicle uses a transponder chip.
What affects the cost of ignition repair?
The main factors are the vehicle, whether the cylinder is repaired or replaced, key programming needs, and time and location. We explain the details before starting work.
Are you available at night or on weekends?
Yes. We operate 24/7. Call (323) 997-8867 any time, day or night.
Do you serve both 91789 and 91788?
Yes. We serve all of Walnut, including ZIP codes 91789 and 91788, as well as surrounding areas of Greater Los Angeles.
