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 isn't recognized, the engine may turn over and then shut off, or not crank at all. That is why a hardware-store copy often opens the door but will not start the car. Programming is what teaches the vehicle to accept a key.
In Sherman Oaks, this need tends to appear at awkward moments: a lost key after dinner on Ventura Boulevard, a last spare that finally stops working, or a car bought used with only one key. Crenshaw Lock Company is fully mobile, so we work where the car is parked, whether that is a Galleria garage, a driveway on the flats, or a curb in the hills.
We have served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the company around automotive and residential work. This page explains how programming works, what affects the cost, and what to expect when you call.
How it works in Sherman Oaks
- 1
You call and describe the vehicle
Call (323) 997-8867 any hour. We ask for the make, model, and year, what kind of key you have now, and whether you have a working key. These answers tell us what equipment the job needs and whether it is a simple add-a-key or an all-keys-lost situation.
- 2
We come to your car
We are fully mobile and have no storefront, so there is nothing to tow to. We meet you at the vehicle, whether it is in a parking structure, a driveway, or on a street. Because the car stays put, you avoid a dealer trip.
- 3
We confirm ownership
Before we cut or program anything, we verify that you own the vehicle or are authorized to have keys made. This protects you and protects every other owner in town.
- 4
We cut the key blade if needed
If you need a new physical key, we cut the blade to your vehicle's code or by decoding the lock. The blade must turn the ignition and doors correctly before the chip is paired.
- 5
We program the transponder
Using professional diagnostic equipment, we connect to the vehicle's immobilizer and register the new key. Depending on the model, this may be a quick add-on or a more involved procedure when all keys are lost.
- 6
We test everything
We start the engine, then test door operation, remote functions where applicable, and a restart. You leave knowing each key works rather than hoping it does.

What affects the price
- Make, model, and year: some vehicles use simple chip systems, while others use encrypted or security-gated systems that require more steps.
- Whether you have a working key: adding a spare is generally more straightforward than recovering when every key is lost.
- Type of key: a basic transponder key, a flip key, and a smart proximity fob are different products with different costs.
- Remote and button functions: if the key also needs lock, unlock, or trunk buttons paired, that adds work.
- Blade cutting: laser-cut or high-security blades take more time and specialized machines than standard cuts.
- Location and time of service: after-hours calls and hard-to-reach locations can affect the quote, which we explain before we begin.

Transponder Key Programming across Sherman Oaks
Sherman Oaks is a car-dependent community, and the vehicles here range from daily commuters on the I-405 and US-101 to newer imports parked in hillside driveways. The Sherman Oaks Galleria district around Ventura and Sepulveda, along with Westfield Fashion Square, means plenty of drivers park in large garages where a lost key is especially inconvenient. We can meet you there, in ZIP code 91403 or 91423, and handle programming at the car.
South of the Boulevard, the Santa Monica Mountains hillsides bring steep, winding roads and gated driveways. If your vehicle is in a garage near Fryman Canyon and you cannot get to a shop, mobile service saves a difficult trip. In the flats, neighborhoods like Chandler Estates have driveways where we can park and work comfortably on the vehicle.
Because we also work on residential and commercial locks, we often help Sherman Oaks customers with both sides of security: a new house key after a purchase, a Ventura Boulevard business rekey, and a spare transponder key for the family car. One call to (323) 997-8867 can cover whichever you need.
