A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your vehicle's immobilizer. If the chip's code isn't recognized, the engine may turn over briefly or not start at all, even though the blade turns the ignition perfectly. That is why a hardware-store copy often fails to start a modern car: it cuts the metal but doesn't carry the right electronic identity. Programming is the step that teaches the car to accept a new key.

In Hidden Hills, this need comes up in ways that are particular to a guard-gated, large-lot community. Families often have several vehicles, from daily drivers to trucks and trailers-pulling SUVs, and keys get misplaced across an acre or more of property, in a barn, or out on a trail ride. Household staff, drivers, and trainers may carry keys too, and when someone leaves, owners often want old keys retired rather than left in circulation.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar, and we are fully mobile. There is no storefront to visit and no need to tow a car anywhere. We bring the equipment to wherever the vehicle is parked, whether that is a motor court, a garage, or beside a stable.

How it works in Hidden Hills

  1. 1

    Tell us about the vehicle and the situation

    Call (323) 997-8867 and give us the make, model, and year, plus whether you still have a working key. Whether you have one key, or have lost every key, changes the approach, so we sort that out first.

  2. 2

    Coordinate access through the gate

    Hidden Hills is guard-gated, with manned entries on Long Valley Road and Spring Valley Road. We work with you on getting cleared in so the visit goes smoothly, since you or your household will usually need to notify the gate.

  3. 3

    Verify ownership

    Before we create a key for a vehicle, we ask for reasonable proof that you own it or are authorized to have keys made. This protects you and is a normal part of responsible automotive locksmith work.

  4. 4

    Cut or prepare the key

    We match the key blank and chip type to your vehicle and cut the blade when one is needed. Some vehicles use a standard chip key, while others use remote-head or proximity styles, and we confirm which applies before any work begins.

  5. 5

    Program to the immobilizer

    Using diagnostic programming equipment, we connect to the vehicle and register the new key. If you want lost keys removed from the system, we can discuss clearing them so only the keys you hold will start the car.

  6. 6

    Test everything before we leave

    We confirm the key starts the engine, locks and unlocks the doors, and that any remote functions work. You get to see it work before the visit ends.

What affects the price

  • Vehicle make, model, and year, since some systems are simple to program and others require more involved procedures.
  • Key type: a basic chip key, a remote-head key, and a proximity or push-button start fob each involve different parts and effort.
  • Whether you have a working key to copy from, or all keys are lost and a new key must be generated from scratch.
  • How many keys you need programmed in one visit, including spares for family members, drivers, or staff.
  • Whether old or lost keys should be erased from the vehicle's memory as part of the job.
  • The time of day, since we serve 24/7 and after-hours calls may be priced differently from scheduled daytime appointments.

Why Hidden Hills chooses us

  • Fully mobile service: we come to the vehicle, so there is no towing and no trip to a shop, which matters on a large property where the car may be in a garage or by a barn.
  • In business since 1987, with owner and lead technician David Shar behind the work.
  • Familiarity with guard-gated communities, so we understand the entry process at places like Hidden Hills and plan the visit around it.
  • Honest guidance on the options, including when a spare made now costs far less hassle than an all-keys-lost situation later.
  • We handle the rest of your property security too, from rekeying main house, guest house, and gates to heavy-duty barn hardware, so one call can cover more than the car.

Transponder Key Programming across Hidden Hills

Hidden Hills sits in ZIP code 91302, tucked beside Calabasas and just off the US-101 (Ventura Freeway) frontage. Inside the gates, the Long Valley Road area, the Spring Valley Road area, and the Round Meadow area each have their own feel, but they share long private driveways, motor courts, and homes set well back from the road. When a key goes missing or a chip stops working, the vehicle is usually somewhere on a property rather than parked on a street, and we bring the work to you.

Equestrian life shapes how keys get lost here. A set can slip out of a pocket in a stable, a tack room, or along the private equestrian trail network, and trucks and trailers that rarely go far can still leave you stranded when a key fails. Because we are mobile, we can work beside the barn or in the driveway without you needing to move anything.

Since entry is through the manned Long Valley Road and Spring Valley Road gates, a little coordination up front helps. If you are also dealing with a failed smart lock, a staff change that calls for rekeying the main house, guest house, and gates, or corroded barn padlocks, mention it when you call at (323) 997-8867 and we can plan to cover everything in one visit.

Transponder Key Programming in Hidden Hills — FAQs

What is a transponder key?
It is a key with a small electronic chip in the head that communicates with your vehicle's immobilizer. The car will only start if it recognizes the chip's code, which is why the key must be programmed and not just cut.
Can you program a key if I've lost all my keys?
In many cases, yes. It is more involved than copying from a working key, but we can often generate and program a new key on site. Call (323) 997-8867 with your vehicle details and we will explain what to expect.
Do I need to bring my car anywhere?
No. Crenshaw Lock Company is fully mobile, with no storefront. We come to your vehicle in Hidden Hills, wherever it is parked on your property.
How does the gate affect the visit?
Hidden Hills has manned entries on Long Valley Road and Spring Valley Road, so you will generally need to let the gate know we are coming. We will coordinate the details with you when you call.
Will you ask for proof of ownership?
Yes. We ask for reasonable verification that you own or are authorized to key the vehicle. It is standard practice and helps prevent unauthorized keys from being made.
Can you remove an old key that was lost or kept by a former employee?
On many vehicles, we can erase old keys from the immobilizer memory so only the keys you currently hold will start the car. This is a common request after household staff changes. Call (323) 997-8867 to ask about your model.
Are you available at night or on weekends?
Yes, we are available 24/7. Mobile service means we can come to you at any hour without timing promises, so call and we will work out the best plan.
Can you also help with the locks around my estate?
Yes. Besides vehicle keys, we handle rekeying homes, guest houses, gates, and heavy-duty barn, tack-room, and paddock hardware. Mention it when you call so we can plan for it.
