Losing a car key is stressful anywhere, but in Signal Hill it tends to happen at awkward moments: at the top of the hill after a walk along the Panorama Promenade, in a parking space outside a hillside townhome, or on a work shift near the Cherry Avenue auto corridor. The city is small and entirely surrounded by Long Beach, yet it is steep, winding and busy with commuter traffic on Cherry Ave, Willow St and the I-405, so being stranded is more than an inconvenience.
Crenshaw Lock Company is fully mobile. We have no storefront for you to visit and no tow to arrange. A technician drives to your vehicle with key-cutting and programming equipment, and the work is done where the car sits. That matters for modern vehicles, because many keys now carry a transponder chip or proximity fob that has to be electronically matched to the car before it will start it.
We have served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. Whether you have lost every key you own, snapped a blade in the ignition, or worn a fob until it barely works, we can replace it without you needing a spare. Call (323) 997-8867 any time of day or night.
How it works in Signal Hill
- 1
You call and describe the situation
Tell us the make, model and year of the vehicle, where it is parked, and whether you have any working key. We will explain what is typically involved for your type of key, and you can reach us at (323) 997-8867 at any hour.
- 2
We come to your vehicle
Because we are fully mobile, a technician travels to you, whether you are at a Hilltop view condo, near Discovery Well Park, or in a dealership lot on Cherry Ave. We make no timing promises over the phone beyond being available around the clock.
- 3
We verify ownership
Before creating a key for any vehicle, we ask for identification and proof that the car is yours or that you are authorized to have a key made. This protects you and protects every other car owner.
- 4
We cut the key, even with no original
Using the vehicle's identification information and the lock itself, we can cut a new blade without an existing key. If the ignition or door lock is worn or damaged, we can address that as part of the visit.
- 5
We program the transponder or fob
Modern keys must be paired with the car's immobilizer. We program the new key or remote on site, then remove lost keys from the system where the vehicle allows it, so a missing key cannot start the car.
- 6
We test everything before we leave
We confirm the key turns the lock and ignition, starts the engine, and that remote functions such as lock, unlock and trunk release work. You leave with a key that is ready to use.

What affects the price
- Type of key: a basic mechanical key, a transponder key, a remote head key, a flip key and a proximity smart fob all require different parts and programming effort.
- Vehicle make, model and year: some manufacturers use more complex security systems that take longer to program than others.
- Whether you have any working key: adding a spare to a car you can already start is usually simpler than creating a first key from scratch when all keys are lost.
- Condition of the locks or ignition: a damaged, worn or broken-off key in the cylinder may need extra work before a new key will function.
- Number of keys needed: having a spare made during the same visit is often more efficient than calling again later.
- Time and location of the call: after-hours service and difficult-to-reach spots can affect the final quote, which we explain before work begins.
Why Signal Hill chooses us
- Fully mobile service: we come to the car, so you never have to arrange a tow just to get a key made.
- Available 24/7: lost keys do not keep business hours, and neither do we.
- Experience since 1987: David Shar and the team have decades of practice with everything from older mechanical keys to current transponder systems.
- No original key required: we can cut and program from scratch when you have lost every key.
- Honest quotes with factors explained: we tell you what affects the price before we start, not after.
- Ownership verification on every job: we check ID and proof of ownership, which keeps the process safe and legitimate.
Car Key Replacement across Signal Hill
Signal Hill sits on a hill above Long Beach, and vehicle needs here reflect that. In the Hilltop neighborhood around Hilltop Park, many residents live in 1990s and 2000s hillside townhomes and view condos built on redeveloped oil land. Parking can be tight, with garages, guest spaces and street parking all in play, and a lost key often means being locked out of both the car and a keypad-controlled building. We can handle the car key at your space in ZIP code 90755 and, if needed, advise on related access issues.
In the Discovery Well district, near Discovery Well Park and the site of the 1921 oil discovery, older homes sit beside active pumping sites and industrial parcels. People who work in the area, or who drive through on Spring St and California Ave, sometimes lose keys on a walk along the Panorama Promenade between the two parks. Wherever the car is parked, we come to it.
The Cherry Avenue auto corridor, home to the Signal Hill Auto Center, adds another need: lost-key and fob programming for inventory or customer vehicles. Dealerships and independent buyers sometimes need an extra key or a replacement for a car that arrived without one. We can work on site along Cherry Ave, and for residents and commuters coming off the I-405 or Willow St, the same mobile service applies at any hour. Call (323) 997-8867.
