Smart Key Services
Smart keys range from $250 to $450 depending on the vehicle. This includes the fob, cutting the emergency blade, programming, and thorough testing of all functions. Exact price quoted on the phone before we dispatch.
Proximity Fob Replacement
Fob went missing or stopped working entirely? The dealer quoted you $400 and a week of waiting. We'll be at your door today.
Proximity fob replacement means pairing a new remote transmitter to your vehicle's body control module so the car recognizes it for passive entry and push-button start. We connect to the OBD-II port using an Autel IM608 or VVDI Key Tool Plus, authenticate to the immobilizer system, register the new fob token, and verify every function: walk-up unlock, push-start ignition, remote lock, panic, and trunk release.
Get your replacement fob programmed today, not next week.
Emergency Blade Cutting
Inside every smart key fob there's a hidden metal blade for emergencies. If yours is missing, broken, or was never cut, you have zero backup when the battery dies.
Every proximity fob contains a small mechanical key blade tucked inside the housing, released by a button or sliding latch. It's designed to manually unlock the driver's door when the fob battery dies or the vehicle's receiver malfunctions.
Make sure your emergency blade actually works before you need it.
Smart Key Battery & Diagnostics
Push-to-start works sometimes but not others? It might be the battery. It might be an antenna, a receiver, or a fob transmitter issue. We figure out which one before you spend money on the wrong fix.
Smart key battery replacement sounds simple, but intermittent proximity issues aren't always a dead CR2032. We start with a full diagnostic: test the fob battery voltage under load, check the fob transmitter output with a frequency counter, verify the vehicle's low-frequency antenna reception at each door handle and trunk lid, and test the in-cabin detection antenna that enables push-button start.
Diagnose the real problem instead of swapping batteries and hoping.
Smart Key System Reprogramming
Dead battery, computer glitch, or module replacement knocked your fobs offline? The fobs are fine. The system just lost sync and needs to be re-paired.
Smart key systems can lose synchronization between the fob and the vehicle after a dead 12-volt battery, a body control module replacement, or even a failed jump-start that sent a voltage spike through the system. When this happens, the car no longer recognizes any of your existing fobs even though the fobs themselves are perfectly functional.
Re-sync your existing fobs instead of buying new ones.
All-Keys-Lost Smart Key Recovery
Zero working fobs for a push-to-start vehicle? The dealer says tow it in and wait ten days. We recover it on site.
All-keys-lost on a smart key vehicle is the highest-difficulty automotive locksmith job there is. With no working fob to authenticate, we bypass the immobilizer from scratch: reading the encrypted EEPROM data from the vehicle's immobilizer module, computing a valid cryptographic seed, generating a new key token, and writing it to a blank fob.
Lost every key? We recover your smart key system from zero, on site.
Multi-Fob Smart Key Setup
Two drivers, three drivers, four drivers. We program every fob in one session so nobody gets erased and nobody gets locked out.
Most modern smart key systems support between three and eight registered fobs simultaneously. Adding multiple fobs in one session is significantly cheaper per unit than programming them individually because the most time-consuming step, establishing the secure OBD-II connection and entering the vehicle's programming mode, only happens once.
Set up the whole household in one visit and save.

Common Smart Key Problems
- Your push-to-start fob stopped being recognized by the car and the dealer wants it towed in for diagnosis.
- You bought a used vehicle with one fob and the seller swore the second one was "around somewhere."
- The car sat for two weeks with a dead battery, and now neither fob unlocks or starts the vehicle.
- You checked the emergency blade slot inside your fob and it's completely empty.
- Your fob works perfectly at the driver's door but the push-button start takes multiple attempts to engage inside the cabin.
