What do Nissan owners in Hidden Hills usually need help with?
Hidden Hills is an unusual place to lose a car key. The whole city is gated and guarded, lots are large, and a lot of the driving is short: house to barn, barn to the community gate, gate to the road. There are no sidewalks or streetlights, and bridle trails run through the city, so a stranded Nissan is often parked somewhere dark, at the end of a long drive or beside an outbuilding, rather than on a busy street.
The Nissan calls you would expect from a place like this fall into a few groups:
Most properties here are large single-family estates, many of them original 1950s and 60s ranch houses that have been rebuilt far bigger, often with their own driveway gates, barns and guest structures. That means a lost key can involve more than one lock. We handle the car side, and if a house, gate or outbuilding lock needs attention on the same visit, it is the same company and the same van. Our Hidden Hills car key replacement page covers every make; this page is about Nissan only.
- You have one key, it is lost, cracked or worn out, and there is no spare to copy from.
- A hardware-store copy opens the doors but the engine will not start, because it was cut without a transponder chip.
- A smart fob says 'key not detected' and you are stuck at the barn, the guest house or the bottom of the driveway.
- A high-mileage Altima, Frontier or Pathfinder has a worn blade or ignition, and the key sticks or turns unreliably.
- A house is being remodeled or rebuilt, a key ring has gone missing among crews and deliveries, and the car key was on it.
How does mobile Nissan key service work at the curb in Hidden Hills?
Nothing gets towed. Our vans carry key-cutting and programming equipment, and we do the work where the Nissan sits, whether that is a driveway, a barn lot or just inside a community gate. Here is the sequence.
If your Nissan turns out to need something we cannot do on site, we tell you plainly at that point instead of leaving you with half a job.
- Call (213) 577-1366. Tell us the model, year, trim, whether it has a metal key blade, a twist knob or a push-button start, and how many working keys you have left.
- Tell us exactly where the car is. Hidden Hills has staffed community gates, so let the gate know a Wilshire Lock & Key van is expected and give us the gate and street to head for.
- We confirm you are entitled to the car by matching ID to the registration or title before any key is made.
- We identify the key system by VIN and by looking at the car, because model year alone does not always settle which chip or fob a Nissan uses.
- We cut the blade where there is one, then program the key or fob to the car, usually through the OBD-II port under the dash.
- We test every key: doors, trunk, remote buttons where fitted, and a full start. You get the keys in your hand before we leave.

Call (213) 577-1366What do the different Nissan key eras mean for your key?
Nissan's immobilizer, called NATS, spread across the line in the late 1990s and early 2000s. Most of those cars used a fixed-code Texas 4D60 chip: Altima 1999-2004, Sentra 2000-2006, Pathfinder through 2004 and Frontier 2002-2004. The 1999-2003 Maxima is a real exception, because catalogs genuinely split between 4D60 and a Philips ID41. We confirm which one by VIN or in person instead of guessing.
The Philips ID46 (Hitag-2) era follows: Murano from 2003, Maxima and Titan from 2004, Pathfinder and Frontier from 2005, Altima 2005-2006, and Sentra and Versa from 2007. The Frontier is the odd one out. It kept a plain bladed ID46 key all the way through 2021.
Smart keys, which Nissan calls Intelligent Key, arrived unevenly. The 2007 Altima made push-button start standard on every trim, while the 2007-2008 Maxima used a twist-knob column switch. The 2008-2013 Rogue offered a twist-knob Intelligent Key above a bladed base key. A short ID47/Hitag-3 window covers the 2013-2015 Altima and, according to conflicting catalogs, possibly the early R52 Pathfinder, so that one we verify in person.
After that, Nissan moved to the 4A/Hitag-AES platform. It showed up first on the 2014 Rogue smart fob, although catalogs list a bladed flip key for the base Rogue S through 2020. It then appeared on the 2015-2016 Murano, Titan, Maxima and Altima, and it is standard on the KR5TXN-series fobs used across 2019 and newer models.
The practical point: two Nissans from nearby years can need completely different keys. A VIN and a look at what you are holding settle it faster than any chart. If you want the brand-wide picture, see our Nissan car key guide.
Can you make a Nissan key if every key is lost?
In most cases yes, but the route depends on the car. Nissan key security is built around the body control module, or BCM. On older NATS cars (4D60, ID41 and most ID46 years), the BCM yields a 4-digit PIN, and professional locksmith tools program new keys through the OBD-II port, even when every key is gone.
Newer models use a rolling scheme. A 22-digit PrePIN from the BCM converts to a 20-digit PIN, which the tool's own calculator or an online service usually handles. On recent keyless models with locked RH850-type BCM or HFM modules, all-keys-lost can require a bench read of the module, or an online calculation, rather than a quick session at the dash. That is a bigger job than adding a spare, and we say so before starting.
Most of these Nissans do not have the FCA-style secure gateway some other makes use, and NASTF SDRM credentials are generally not a hard requirement through the 2010s. The real limit is how new the vehicle is. Aftermarket coverage for 2022-and-newer trucks and SUVs, and the 2025-and-newer Murano, is still maturing, so some of those jobs may be dealer- or specialist-only until tool support settles. If yours is one of them, we will tell you honestly. If you have already lost the only key, our lost car key replacement page explains the broader process.

Call (213) 577-1366Is it really the key? Nissan problems that look like key trouble
Before cutting anything, we check whether the key is actually at fault. These are the Nissan problems we see most often, and several of them are not cured by a new key:
A no-start with a flashing key light on a 2007-2014 push-button Altima, Maxima or Murano is a good example. It looks like a key problem, but the electronic steering-column lock can be the cause, so we diagnose before we program anything.
- Electronic steering-column-lock (ESCL) failures on 2007-2014 push-button Altima, Maxima and Murano models, which cause a no-start and a flashing key light that mimics a key fault.
- A NATS security light that stays on solid, meaning the immobilizer is not reading a worn or badly cloned chip.
- Worn ignition lock wafers and key blades on high-mileage bladed-key cars and trucks.
- A dead smart-fob battery that produces a 'key not detected' message. Holding the fob against the start button or knob usually still starts the car.
- Hardware-store copies cut without a transponder, which open the doors but will not start the engine.
- Used or online-bought fobs whose FCC ID and IC numbers do not match the original and refuse to pair. Wrong numbers are a common cause of failed pairings.
What affects the cost of a Nissan key replacement in Hidden Hills?
We do not publish a flat figure, because Nissan keys vary too much for one to be honest. These are the things that move the cost up or down:
We talk through the cost on the phone once we know your model, year and key type, and we confirm it before work begins. If you are weighing options, a spare made while you still hold a working key is usually the more economical route compared with an all-keys-lost job later.
- Key type: a plain bladed transponder key, a flip key, a twist-knob Intelligent Key and a push-button smart fob are different hardware with different costs.
- Spare versus all keys lost: copying from a working key is simpler than creating the first key from the car's computer.
- Module work: a locked BCM that needs a bench read or an online PIN calculation adds time and tooling.
- The right fob: fobs with the wrong FCC or IC numbers often fail to pair, so buying the correct part matters more than buying a cheap one.
- How many keys you want made in one visit.
- Where the car is and when you need us. We are based in Westwood, and Hidden Hills is about 24 miles from our base.

Call (213) 577-1366Dealer or mobile locksmith: which makes sense for your Nissan?
Both are legitimate, and for some Nissans the dealer is the right call. The newest generations, meaning 2022-and-newer trucks and SUVs and the 2025-and-newer Murano, have aftermarket tool support that is still catching up, and some jobs there may be dealer- or specialist-only. If your car is in that group, we will say so on the phone and not take your call as a chance to experiment.
For the large range of Nissans from the NATS era through the 2010s, a mobile locksmith can usually do the whole job where the car is parked. That saves arranging a tow from a gated estate, and it means a lost key at the barn or at a bridle-trail lot does not become a two-stop errand. A locksmith can also work outside business hours, and we answer 24 hours a day. Whichever route you choose, ask for the job to be explained in plain terms before it starts.
Why call Wilshire Lock & Key for a Nissan key?
We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans that cover 140 cities across Los Angeles and Ventura counties. When you call (213) 577-1366, you reach us, not a dispatch middleman who resells the job to whoever is closest. Our owner and lead technician, David, oversees the work.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you hire for it. That is a sensible habit, especially when someone is making a key to a car worth a great deal.
If you are still deciding what you need, our car keys overview lays out the services, and the key fob replacement page is useful if you already have a car and only need a new remote.
Nissan key service around Hidden Hills, ZIP 91302
Hidden Hills is one gated city, but it is spread out, and where you are inside it changes the practical details. Along the Long Valley Road corridor, near the main gate, a van can reach you quickly after the gate is told we are coming. Out on Round Meadow Road, near Round Meadow Elementary School, and on Jed Smith Road, you are more likely to be on a long private drive, so tell us which gate and which driveway. Near the west edge by Upper Las Virgenes Canyon Open Space, and at the south edge near The Commons at Calabasas, directions can be less obvious, so a cross street or a landmark such as the Hidden Hills Community Center helps.
Equestrian properties add their own scenes. Cars end up beside barns, tack rooms and guest structures, far from the house, often after dark on roads with no streetlights. If you are locked out rather than keyless, our car lockout service is the page to read first.
Hot, dry summers and occasional Santa Ana winds off the Simi Hills mean sun exposure and heat cycling are hard on estate gates and exterior hardware. If your driveway gate keypad or intercom lock is acting up too, mention it when you call. For the full picture of what we do in the city, see our Hidden Hills locksmith page, or contact us directly.

Frequently asked questions
Can you replace a Nissan key in Hidden Hills if I have lost all of them?
Usually yes. Older NATS Nissans are programmed through the OBD-II port using a PIN from the body control module. Newer keyless models can need a module bench read or an online PIN calculation, and the newest trucks and SUVs may be dealer- or specialist-only. We tell you which case yours is on the phone.
Will a hardware-store copy start my Nissan?
Not if the car has a transponder. A plain copy often opens the doors but will not start the engine, because the immobilizer does not recognize it. A proper copy needs the right chip and programming to the car.
My push-button Nissan says 'key not detected.' What should I try?
Hold the fob against the start button or twist knob and try again, since that usually still works when the battery is dead. If it does not, the fob or the car may have a fault, and we can test both.
Is a flashing key light always a bad key?
No. On 2007-2014 push-button Altima, Maxima and Murano models, a failed electronic steering-column lock can cause a no-start with a flashing key light. A new key will not fix that, so we diagnose first.
Can you program a key fob I bought online?
Sometimes. Fobs with the wrong FCC ID or IC numbers are a common reason pairing fails, so check those numbers against your original. If you are unsure, tell us the numbers when you call and we will say whether it is worth trying.
Do I need the dealer for a brand-new Nissan?
Possibly. Aftermarket tool support for 2022-and-newer trucks and SUVs and the 2025-and-newer Murano is still maturing, so some jobs may be dealer- or specialist-only. We confirm by VIN and tell you honestly if yours falls into that group.
Do you come into the gated parts of Hidden Hills?
Yes, our vans serve Hidden Hills. Because the community gates are staffed, tell the gate we are on our way and give us the gate, street and driveway so we can find the car.
Are you available at night?
Yes. Our phone is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366, and that matters on a city with no streetlights where a lost key often turns up after dark.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start. Ask them to explain the job and the cost in plain terms before work begins.
