Question 1

What is a smart key?

Accepted Answer

A smart key (proximity key, KEYLESS-GO, Intelligent Access, Advanced Key, Comfort Access) is a fob that communicates with the vehicle over short-range RF, unlocking the doors when you approach and enabling push-button start. Most modern cars from 2015+ ship with them; some as early as 2005.

Question 2

Can you program smart keys for my vehicle?

Accepted Answer

Yes. Falcon Locksmith programs proximity smart keys on-site across Denver Metro for many Toyota, Lexus, Honda, Nissan, Ford, Chevrolet, Hyundai, Kia, Mercedes-Benz, BMW, Audi, VW, and Porsche vehicles. Support is year, model, and platform dependent, so I verify your VIN first.

Question 3

How much does smart key programming cost?

Accepted Answer

Service call starts at $49; smart keys cost more than basic transponder keys because both the hardware and the programming procedure are more complex. Every job is quoted before we begin.

Question 4

Can you make a smart key without the original?

Accepted Answer

Yes. We originate smart keys from the immobilizer for most vehicles when all keys are lost. Late-model European vehicles take the longest, and some platforms still require a dealer. I confirm from your VIN whether your vehicle can be completed on-site before you book.

Question 5

Can you program aftermarket smart keys?

Accepted Answer

Yes for most vehicles. OEM-quality aftermarket smart keys work on many mainstream makes at meaningful cost savings. A few late-model European models reject aftermarket electronics — we verify compatibility before you buy.

Question 6

Will my old smart key still work after a new one is programmed?

Accepted Answer

For duplicates, yes — both keys operate the vehicle. When we originate keys after all-keys-lost, the module is typically cleared and reprogrammed so any missing key is disabled. If a key is genuinely lost, you want it dead.

Question 7

Why does my smart key work sometimes but not always?

Accepted Answer

Usually a weakening fob battery, damaged antenna coil, or interference from wireless chargers and USB hubs. We diagnose on-site and either replace the battery, repair the fob, or reprogram — whichever your fob actually needs.

Question 8

Do smart keys have a mechanical backup?

Accepted Answer

Most smart keys hide a mechanical emergency blade for door access when the fob battery is dead, though it varies by model. That blade doesn't start the engine, but it gets you inside. When your key includes an emergency blade, I cut and pair it with the new smart key.

Question 9

How long does smart key programming take?

Accepted Answer

Duplicate smart keys: 30–60 minutes on-site. All-keys-lost smart key origination: 60–120 minutes for most vehicles, longer for late-model European models.

Question 10

Can you fix a smart key that fell in water?

Accepted Answer

Sometimes. If the electronics are corroded beyond repair, we transplant the internals into a fresh housing or program a replacement. Battery removal and thorough drying within the first hour dramatically improves the odds of saving a wet fob.
