A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car's immobilizer. If the chip's code isn't recognized, the engine won't start, even when the blade turns the ignition freely. That is why a hardware-store duplicate often unlocks the door yet leaves you stranded. Programming is the step that teaches the car to accept the key.
In Redondo Beach this comes up in very ordinary moments: a spare lost after a day on the Redondo Beach Pier, a only-key situation after parking along Pacific Coast Hwy, or a used car bought with a single worn 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 sitting and do the work there.
Since 1987 our owner and lead technician, David Shar, and our team have served Greater Los Angeles and Ventura County. We are available around the clock, which matters when a key problem happens late at night after a harbor dinner or before an early commute up Aviation Blvd. Call (323) 997-8867 and tell us the make, model and year, and we will explain what your car needs.
How it works in Redondo Beach
- 1
Tell us about the vehicle
When you call (323) 997-8867, we ask for the make, model and year, and whether you still have any working key. This tells us what kind of system your car uses and whether we are adding a spare or replacing every key.
- 2
We come to your car
Because we are fully mobile, we drive to your location in Redondo Beach: a driveway in The Avenues, a street in Hollywood Riviera, or a parking structure near King Harbor. Nothing needs to be towed.
- 3
Confirm ownership
Before programming a key we verify that you are entitled to the vehicle, typically with ID and registration or title. This protects you and every other owner from misuse.
- 4
Prepare or cut the key
If the key needs cutting, we cut the blade to match your locks. We also check that the transponder chip is compatible with your vehicle before any programming begins.
- 5
Program to the immobilizer
We connect our programming equipment and register the new key with the car's immobilizer. Depending on the vehicle, we may also add or remove keys on its list, which is useful if an old one is lost.
- 6
Test everything
We start the engine, test the door locks and any remote functions, and check every key you now have. You leave with keys that have been proven to work, not just keys that look right.

What affects the price
- Vehicle make, model and year, since some immobilizer systems are far more involved to program than others.
- Whether you are adding a spare key or have lost all keys, which changes how much work the car requires.
- The type of key: a basic chip key, a flip key, or a proximity-style key with remote functions.
- Whether the key blade needs to be cut, and how complex the cut is.
- Time and location of the call, including late-night or after-hours service.
- Whether any lost keys should be removed from the car's memory as part of the job.

Transponder Key Programming across Redondo Beach
Redondo Beach is split between South Redondo (ZIP 90277) and North Redondo (ZIP 90278), and car-key problems look a little different in each. In the south, around Riviera Village, the Redondo Beach Pier and King Harbor, vehicles spend long days parked near the water, and keys get dropped, misplaced or exposed to salt air and sand. Many residents park on narrow streets in Hollywood Riviera, where a call-out right at the curb saves the hassle of a tow up and down the hills.
North of Artesia Blvd, neighborhoods like El Nido, Golden Hills and The Avenues are filled with attached townhomes and small-lot homes where cars often sit in shared garages or tight driveways. ZIP 90278 is also where many commuters rely on Aviation Blvd, Inglewood Ave and Torrance Blvd. If your only key stops working there, we can come to the garage or the street and program a replacement.
We also see requests near Veterans Park, Seaside Lagoon and the harbor lots, where visitors and boat owners leave vehicles for hours. Wherever the car is in Redondo Beach, call (323) 997-8867 and we will come to you.
