Lost All Car Keys in Mentone: Search, Secure, Replace
Short answer: Treat lost all car keys as a security problem first and a transportation problem second. Anyone holding your keys and registration knows what you drive and where you live. Lock the car, file a police report if theft is possible, and have us make new keys in Mentone so the missing ones stop working.

There's a particular kind of quiet that follows the words 'I can't find any of my keys.' If you've lost all car keys, including the spare you swore was in the kitchen drawer, the first move is to slow down. Retrace your steps in order: the pockets of whatever you wore yesterday, the bag you carried, the car seats and floor mats, the place you last remember using the fob. Phone the last two places you visited in Mentone and ask staff to check lost and found. Give that search an honest ten minutes. If nothing turns up, Julian's Locksmith can take over at (951) 903-3193. We come to the car, confirm it's yours, and build you a new set.
What to know first in Mentone
Locksmiths sort car-key jobs into two families. In the first, a working key exists and we copy or clone it. In the second, the car has no key left to learn from, and the work starts from scratch. Lost all car keys belongs to the second family, and it has a few extra moving parts. First we need the cuts: for many makes we read the driver's door lock with a decoder, and for others we request a code tied to your VIN. Next comes the blade, cut on a machine in the van. Then the car has to accept the key. Most vehicles built since the late 1990s carry an immobilizer, a small computer that checks a chip in the key before it lets the engine run. Teaching it a new chip when no old key is present takes the right software, a secure connection to the OBD-II port and, on some brands, an access code. That's why the job takes longer than a spare, and why we ask for proof of ownership first. It also explains the upside: the missing keys can be removed from the system in the same visit.
Work included on a typical visit
- Entry first, in case the keys are inside. People often lose all car keys by locking them in a coat pocket on the back seat or in the trunk. We open the vehicle without damage, let you look under mats and between cushions, and only then move to key making. Nothing gets cut until we're sure nothing is left to find.
- House, mailbox and gate keys that vanished with the ring. Mailbox keys, storage unit keys and gate fobs often ride along on the same ring. We can cut a new key or replace a lock when the model allows, and we'll tell you when someone else controls it. Cluster mailbox locks typically belong to the Postal Service, and HOAs or landlords may need to authorize changes.
- Stolen keys and the police report. If your wallet and keys were taken together, a thief may know your address and your car. After the report is filed, we can erase the stolen keys from the car in Mentone and rekey the home, treating both as one security job. Ask your insurer whether they want to see our work order.
- Dealer-only vehicles and what we can still do. Some cars refuse every route except the dealership: certain late-model European brands, a few electric vehicles, and some trims with proprietary security. We say so at the start. We can still open the car, record the VIN, list the paperwork the dealer will ask for, and help you plan a tow.
- A full set instead of one key. The best moment to build a backup is while we're already connected to your car. Programming several keys in one session takes far less time than starting over later, and it gives you a spare to hand to a trusted neighbor, relative or coworker in Mentone.
What's different about Mentone
Inland summer heat raises the stakes while you search. Cars parked in direct sun become ovens, so if a child or pet is inside a locked car, call 911 before anyone else. For everyone else, find shade and water, finish a methodical search, and call us from somewhere cool. Heat also stresses tired fob batteries, so test any fob you find with a fresh coin cell before assuming it's dead.
Trail days produce keys that slide out of pockets and drop into brush. If you're hiking above Mentone and lose them, don't retrace a steep trail in the dark or in high wind. Mark the spot, return at daylight, and call us from wherever you have cell signal. A car parked at a trailhead can usually be keyed on site, though a dirt road may limit where our van can go.
Commuters who've lost all car keys tend to find out at the worst moment: standing at a park-and-ride in the dark, or at 6:40 a.m. with a train to catch. Our day starts at 6:30 a.m. every day, so an early call from Mentone is workable. Arrange a ride first, tell your employer you'll be late, and leave the car locked. If you take transit, we can meet the car after work with your ID and registration in hand.
Example situations
- For example, a leased SUV near Mentone Branch Library has a few months left on its lease, and the driver loses both keys. The lessor technically owns the vehicle, so we ask for the lease paperwork and the finance company's authorization along with the driver's ID. We'd make new keys, and you'd keep the work order, because lease-end inspections often count missing keys.
- A newer electric SUV in Mentone comes with a phone key and a key card, and the card disappears from a wallet. Technically not every key is lost, but one dead phone battery would strand the car. We'd explain which backup options we can add and which only the manufacturer's service center can authorize, rather than start a job the car won't accept.
- Say the family's second key was lent to a sibling two years ago and never came back, and now the teenage driver loses the only one left. The household has lost all car keys, and nobody can find the old one either. We'd verify the parent's ownership, make two new keys and erase the missing ones, then suggest keeping a spare at home instead of in a backpack.
- Picture a former roommate who moved out and took both keys to your hatchback along with theirs by mistake. They live out of state and aren't answering, so you've effectively lost all car keys without losing anything. Because the car is registered to you, we can make new ones and erase the missing ones. If the same ring held an apartment key, you'd talk with your landlord about the lock.
From your call to the finished job
- Do a real search, then call us. Tell us whether the car is locked, whether it was running normally, and where it's parked in Mentone. If it's in a gated lot, a garage or on a dead-end street, give us details. We'll size up the job by phone and say plainly if the make is dealer-only before anyone drives out.
- Lock down what the keys protect. If you lost the keys while out of the area, ask someone you trust to watch the car, keep it locked, and photograph it where it sits. Those photos help with insurance claims and show nothing was disturbed before we arrive to start the job.
- Verify ownership. We compare your ID with the registration or title, and we look at the VIN on the dash and door jamb, so the key we cut is for the car in front of us. A car registered to a relative, employer or lessor needs their authorization before we begin.
- Recover the key cuts. With no original to copy, we read the cuts from the car itself. A decoder tool turns the driver's door lock and shows each position, or we request a key code tied to the VIN from the secure sources locksmiths use. Then we cut a fresh blade on the machine in the van.
- Program the new key and retire the old ones. This is the technical center of the visit. The programmer talks to the immobilizer, supplies any required security access, and adds the new transponder or fob. We keep the car's battery steady throughout, because a voltage dip mid-process can leave the system in an awkward state.
- Test, add a spare and close the loop. We test every key in the door, the trunk and the ignition, and we start the car more than once. Before we pack up, we talk about a second key, where to store it, and what to do if the old keys reappear. You get a work order showing what was done.
What affects the cost
- The kind of key your car uses. Parts and programming gear differ by key family. Factory-quality blanks cost more than economy ones, and some brands need special software that adds time. We quote the key you actually need and explain your choices, such as a plain chip key plus a separate remote instead of an all-in-one.
- Whether any key survives somewhere. Even a valet key, a dealer envelope with a key code, or a phone key that still works can reduce the work involved. Mention everything that still exists. We'd rather quote a smaller job than perform a larger one you didn't need.
- Where the car sits and when you call. Access matters as much as mileage. Parking structures with height limits, gated lots that need a guest code, and a busy shoulder along Lugonia Avenue all slow the work. Tell us the rules before we arrive, and we'll build the time into the price.
Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in Mentone.
Advice before you book
- If your fob carried a garage-door or gate button, remember those remotes are gone too. Most openers let you erase every remote from memory with the learn button, which stops a stranger from opening your garage. Your opener's manual shows the steps for your model.
- Skip the social post announcing 'lost my keys at the lake' with a location and a car description. It tells strangers where an unattended car sits. Ask friends privately, or use a neighborhood group that doesn't show your address, and keep the details vague until the car is secure.
- Test each new key before we leave: lock, unlock, trunk, ignition, and push-button start if it applies. Start the engine several times, shut it off and restart. A problem found at the curb costs minutes. One found on the freeway costs a tow.
- Search in a set order so you don't repeat yourself: pockets of the last two outfits, every bag, the car seats and trunk if it's open, the kitchen counter and entry table, then the trash and recycling. People who work through a list find keys faster than people who wander the house in circles.
What not to do
- Skipping the house locks. If your ring held a house key and any identification that points to your address, treating this as only a car problem leaves the front door open. A rekey is usually modest compared with the exposure.
- Waiting days after you've lost all car keys in hope that they'll turn up. While you wait, the car sits unattended, possibly with a registration card that shows your address, and a missing set could be in someone else's hands. Give the search a sensible window, then act.
- Driving away without a full test. A key that opens the door and cranks the engine can still fail at remote start, at the trunk release, or when you shut the engine off and try again. Insist on a complete check while the locksmith is still there.

Mornings start early here: phones are answered from 6:30 a.m. seven days a week, which suits commuters who discover a missing key in the driveway and shop owners who can't open the front door. Saturday and Sunday are no different. Every day runs to 11:30 p.m.
Safes get the same scrutiny. Before drilling or manipulating one, we need reason to believe it's yours: a purchase record, the fact that it sits in your home or business, or estate paperwork if you inherited it. A safe exists to keep people out, so proof of ownership isn't optional.

Frequently asked questions
How can I make sure the lost keys never start my car?
Ask us to run the full all-keys-lost routine, which on most cars removes old keys from the immobilizer while registering the new ones. Ask to see the key count at the end. Where a car can't erase keys, we discuss other options, such as changing the ignition and door cylinders on an older vehicle.
I found my old keys after you made new ones. Can I use them?
On most cars programmed with an all-keys-lost routine, the old keys no longer start the engine, though the metal blade may still open the doors. Don't count on it, though. Test them with us, or leave them off the ring. Keeping them as a keepsake is fine. Putting them back into daily use is not worth the confusion.
Do I need to tow my car to a dealership?
For most makes, no. We come to the car, read the lock, cut a key and program it in your driveway or parking lot. A tow is only needed for dealer-only models, such as certain late-model European brands, some electric vehicles and a few trims with proprietary security. We tell you at the start so you don't tow when you don't have to.
Can you make keys where my car is parked at work or at the airport?
Usually, yes. We can work in office lots, parking structures and driveways. Check with the property manager about vehicle access and any height limits, and tell us the level and stall. If the lot requires a visitor pass or a security escort, arrange it before we arrive. Airport lots may have their own rules, so ask first.
What if my keys are inside the locked car?
That's a better problem than losing them for good. We open the car without damage, using an air wedge or a Lishi pick, and you look inside. Many drivers find keys under a seat, in a jacket or in the trunk. If nothing is inside, we go straight to making keys, with the car already open and your paperwork in hand.
How far do you travel for a lost-keys call?
We're based in San Bernardino and drive across the Inland Empire, San Gabriel Valley, Pomona Valley, north Orange County and southeast Los Angeles County. If you're in Mentone, call and we'll give you an honest arrival estimate and tell you what the drive adds to the quote before we leave.
How far is Mentone from your base?
Mentone is about 20 miles from our San Bernardino base, roughly 27 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
