Lost Car Key Replacement in Simi Valley, CA.

This page covers lost car key replacement in Simi Valley, from what is included to what to have ready.

All-keys-lost service is making a car key from nothing: no working key to copy, no fob to clone. We establish the cuts from the key code tied to your VIN, or by decoding the door lock when no code is available, cut the blade, and then run the manufacturer's all-keys-lost procedure to register a new transponder or fob with the immobilizer. It is the most involved key job a vehicle can need and the one where ownership proof matters most.

The technician comes to your address in Simi Valley, in Ventura County. The dispatch line at (888) 492-0666 is answered around the clock, and the dispatcher confirms the details and an ETA before anyone is sent.

• Ownership verification before anything is cut: your ID matched to the registration, title or insurance card
• Key code lookup from the VIN through authorized channels where the manufacturer permits, or decoding of the door lock cylinder to recover the cuts
• Entry into the locked vehicle without damage if you are locked out as well
• Blade cut to code and, for push-to-start cars, the emergency blade cut for the fob
• All-keys-lost immobilizer procedure through the diagnostic port, including any security PIN retrieval and built-in wait the make imposes
• Start test, door and trunk test, and remote function test on the new key
• A spare cut and programmed in the same visit while the equipment is connected, which avoids a second all-keys-lost job later

• Photo ID and the registration or title in your name (an insurance card with the VIN also helps); if the paperwork is inside the car, we check it once the door is open
• Year, make, model, trim and VIN
• Whether the car started with a turned key or a push button, and whether the old key had remote buttons
• If the vehicle was bought recently, inherited or purchased at auction: the bill of sale plus the title transfer paperwork
• Whether the car has been sitting; a low battery delays programming
• For a rental, lease or company vehicle: the agreement or written authorization; some lessors require their own process for lost keys

Typically 45-120 minutes. Common Japanese, Korean and domestic vehicles with an available key code are at the short end. Decoding a door lock instead of using a code, a make that enforces a security wait of several minutes before a new key is accepted, and European models with extended procedures push toward the long end, and some vehicles have to be scheduled rather than done on a first stop.

• Dealer-only all-keys-lost systems: most Mercedes FBS4 (about 2015 and newer), many 2020-and-newer BMW, Audi, Porsche and Range Rover models, and some current Volvo and Jaguar systems. We tell you on the phone and will not dispatch a van that cannot finish the job
• Many 2018-and-newer Chrysler, Dodge, Jeep and Ram vehicles need security-gateway authorization before an all-keys-lost procedure
• Some older European vehicles (BMW EWS, early VW and Audi immobilizers, pre-2010 Mercedes) need a module read on the bench rather than a port procedure; we confirm by year
• Tesla key cards cannot be originated by a locksmith; if every card and phone key is gone, Tesla service pairs a new one
• Key codes are not available for every make and year; where the lock has to be decoded, a damaged or previously replaced door cylinder can give cuts that no longer match the ignition
• A dead 12V battery or a vehicle that has been in storage must be brought to steady voltage before programming; we can jump or charge it, but a battery that will not hold a charge needs replacing first
• We do not originate keys without ownership proof; a recently purchased vehicle needs the bill of sale and the transfer paperwork, not just a verbal account

The quote depends on the key type (plain transponder, remote-head, laser-cut or proximity fob), the make and model year and how long its all-keys-lost procedure runs, whether a key code is available or the lock has to be decoded, whether we also have to open the car, whether a security PIN has to be retrieved, the number of keys you want, and the time of day. An all-keys-lost job costs more than adding a key to a working one, which is why we suggest a spare while we are there.

The dispatcher gives you a range on the phone, and the technician confirms a written quote before any work starts.

Payment is by Cash, Credit Card, Debit Card, Apple Pay and Google Pay, and you receive an itemized receipt listing what was done.

• Transponder keys across TI 4C/4D/DST-AES, Philips ID46 and Hitag, Megamos 48 and AES, ID47, ID49 and 8A chip families
• Remote-head and flip keys with the blade cut from code
• Proximity and push-to-start fobs with a cut emergency blade
• Laser-cut high-security blanks: HU66, HU92, HU100, HU101, HON66, TOY48, TOY51, NSN14, HY22, KIA9
• Edge-cut blanks for pre-immobilizer vehicles
