A fob is only half a key until the car knows it. We pair new, spare, and replacement fobs to your car at your curb, and prove every button before we leave.

Lake Forest Locksmith
Somewhere between the dealer parts counter and the online marketplace, a lot of Lake Forest drivers end up holding a fob their car ignores. Programming is the step that marries the two, and it takes the right tool, the right sequence, and access to the car's security system. That is our daily work.
We program remote fobs, remote head keys, and proximity smart keys for the makes that fill South OC: Ford, Chevrolet, Toyota, Honda, Nissan, Jeep, Hyundai, Kia, and many more. Bought your fob online? Bring it. If it is the right part, we pair it. If it is not, we will show you exactly why and offer ours with programming included, no hard feelings either way.
What's included
Pairing is the visible part. Testing, security cleanup, and honest advice about your fob come with it.
Honest pricing
| Service | Typical price range |
|---|---|
| Fob programming only (your fob) If it pairs, you pay this and go | $65 to $95 |
| Remote fob supplied and programmed Most common makes | $120 to $190 |
| Smart proximity key, supplied and programmed Push-button start cars | $160 to $290 |
| Second fob programmed, same visit The smart time to add a spare | $45 to $75 |
| Fob battery and contact service When that is all it needs | $15 to $25 |
Programming-only pricing assumes your fob is the correct part for your car. If it will not pair because it is the wrong frequency or board, we charge a small diagnostic fee only if we quoted one on the phone first. Model years matter: some 2021 and newer cars restrict key programming. We check your exact model when you call, so the quote and the plan are real.
How it works
Year, make, model, and where the fob came from. A photo of the fob by text helps.
Battery voltage, signal output, board condition. Many dead fobs are five-minute fixes.
Our programmer talks to the car and introduces the fob to its security system.
On request, old fobs are cleared so only the keys in your hand work.
Lock, unlock, trunk, panic, and start. You press them all.

Fob trouble around the foothills
The Whiting Ranch and O'Neill trails eat fobs: dropped on Portola Parkway crossings, soaked on creek trails, or left on a roof at the trailhead lot. Lake Forest Sports Park adds its own version, a fob through the wash in a jersey pocket. These are weekly calls for us, and most end with a fresh programmed fob the same day.
Laguna Woods keeps us busy differently: aging fobs with worn buttons on well-kept older cars, and grandchildren visiting with a spare fob that needs pairing before the drive home. Village clubhouse lots are a regular stop. Whatever the story, we bring the programmer to the car and sort it there.

Good questions
Usually it is the battery or worn button contacts, both cheap fixes. We test the signal strength and tell you which it is before quoting anything bigger.
If it matches your car's part number and frequency, yes. About half of online fobs are correct; bring it and we will know within minutes. Our programming-only price applies when it pairs.
A lost fob can still open and start your car. When we program your replacement, ask us to erase the missing one from the car's memory. It takes minutes and closes the hole.
Most fobs pair in 15 to 30 minutes. Some newer cars add security delays built into their systems, which we will warn you about when you book.
For most makes and years, no. Our equipment covers the great majority of cars on South OC roads. A few very new models are restricted; we check yours by VIN and tell you straight.
Yes. Programming does not need a running engine, just a healthy 12-volt battery, and we carry jump packs for cars that have sat.
