Most cars built since the late 1990s will not start with a plain metal key. Inside the plastic head of the key is a small transponder chip, and the car's immobilizer checks for a matching code before it lets the engine run. If you have lost your only key, or you want a spare before that happens, the new key has to be cut and then electronically introduced to the car. That second step is transponder programming.

In Glendale, we see this need in every kind of setting: a commuter whose spare disappeared somewhere along the SR-134, a shopper who dropped a key fob in the garage at the Glendale Galleria or The Americana at Brand, or a renter in a downtown apartment building whose roommate drove off with the only working key. Crenshaw Lock Company is fully mobile, so there is no shop to tow your car to. We bring the equipment to wherever the vehicle is parked.

David Shar has run the company since 1987, and the work has changed a lot in that time, from simple cut keys to encrypted chips and push-button start systems. We will tell you plainly what your particular vehicle needs, what can be done on site, and what, if anything, is better handled by a dealer. We would rather give you an honest answer than sell you a service that will not work.

How it works in Glendale

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 any hour and tell us the make, model, year, and where the car is parked. Let us know whether you have a working key, or whether all keys are lost. That determines the approach and what we bring.

  2. 2

    We drive to your location

    Because we are fully mobile, we meet you at home, at work, in a parking structure, or at the curb. Wherever you are in Glendale, from a hillside driveway to a downtown garage, the work happens at the vehicle.

  3. 3

    Verify ownership

    Before we create or program any key for a vehicle, we ask for reasonable proof that the car is yours, such as ID matched to registration or title. This protects you and keeps keys out of the wrong hands.

  4. 4

    Cut and prepare the key

    If you need a new physical key, we cut it to the car's lock, either from the existing key, by code, or by decoding the lock when no key is available. The transponder chip is then matched to the correct type for your vehicle.

  5. 5

    Program to the immobilizer

    We connect programming equipment to the car's diagnostic port and register the new key with the immobilizer. Depending on the vehicle, we may also add or erase keys so a lost one can no longer start the car.

  6. 6

    Test everything

    Before we finish, we test the key in the door, the ignition or start button, and any remote functions. You see it start the car, and we confirm every key you own still works.

What affects the price

  • Make, model, and year of the vehicle, since some manufacturers use far more complex security than others
  • Whether you have a working key to copy or all keys are lost, which changes how much setup the car requires
  • The type of key: a basic chip key, a flip key, a remote head key, or a proximity smart key with push-button start
  • Whether the vehicle needs a new physical key cut, such as a high-security laser-cut blade
  • How many keys you want programmed in one visit, including spares and removal of lost keys
  • Time of day and how far we travel to reach you, since we serve customers around the clock

Why Glendale chooses us

  • Fully mobile service: we come to the car, so you avoid towing a vehicle that will not start
  • Available 24/7, including nights, weekends, and holidays, for the moments keys disappear at the worst time
  • In business since 1987, with experience spanning older chip systems through modern smart keys
  • Honest assessment: if your vehicle is one that truly requires a dealer, we say so rather than promising what we cannot deliver
  • Ownership verification on every job, which protects you from theft and unauthorized key duplication
  • One company for the whole picture: car keys, house lockouts, and rekeying, so you do not need separate vendors

Transponder Key Programming across Glendale

Glendale is a car-dependent city wrapped by the SR-134, the SR-2, and I-5, and many residents park in situations where a lost key is a real problem. In the 1960s to 1980s apartment and condo buildings near downtown, shared or tandem parking and tight garages mean a car that will not start can block others. We program keys right in the space, working carefully around neighbors. Around 91203 and 91204, close to Brand Boulevard and Central Avenue, we often meet people in garages and street parking.

Up in the hills, Verdugo Woodlands and the streets below the Verdugo Mountains have steep driveways and narrow roads where towing a no-key vehicle is awkward and sometimes risky. Mobile programming avoids that entirely. Down in Rossmoyne and Adams Hill, where 1920s Spanish and Mediterranean Revival homes line the streets, we are used to working in older neighborhoods where cars often sit on the street or in detached garages.

We also help visitors and workers who lose keys while out. Whether you were at the Alex Theatre, the Brand Library, Forest Lawn Memorial Park, or shopping on Brand Boulevard, call (323) 997-8867 and tell us where the car is. If you are in a ZIP such as 91201, 91205, or 91206, the process is the same: we come to you and program the key on site.

Transponder Key Programming in Glendale — FAQs

Can you program a transponder key if I lost every key to my car?
In many cases, yes. An all-keys-lost situation takes more work than copying an existing key, but it is often doable on site. Call (323) 997-8867 with your vehicle's make, model, and year, and we will tell you what to expect.
Do I need to tow my car to Glendale for programming?
No. We are fully mobile and come to your vehicle, whether it is in a home driveway, an apartment garage, or a lot near the Americana at Brand. There is no storefront to visit.
Will a hardware-store key work in my car?
A cut-only key may open the door, but if your car has an immobilizer it will not start the engine unless the chip inside the key is programmed to the car. That programming is the service we provide.
Can you program keys at night or on weekends?
Yes. We operate 24/7. If you are stuck late at night or on a holiday, call (323) 997-8867 and we will arrange service.
Do you have to verify that I own the car?
Yes. We ask for reasonable proof of ownership, such as ID and registration or title, before making or programming a key. It protects you as the owner.
Can you erase a lost key so it cannot start my car?
On many vehicles, yes. When we program new keys, we can often reset the immobilizer so that only the keys you currently hold will start the car. This is a good idea if the lost key could be in someone else's hands.
Do you also program smart keys and push-button start fobs?
Many of them, yes, though capability depends on the vehicle. Some newer or luxury models have restrictions. Tell us your car's details when you call and we will be upfront about what is possible.
How is the price determined without a flat number?
The cost depends on your vehicle, the key type, whether you have a working key, how many keys you need, and when and where we are called. We explain the factors and the total for your situation before starting work.
