Proximity Keys / Smart Keys
20-Min Average Response Time Actual arrival varies by location, traffic, and call volume.
Proximity keys, also called smart keys or keyless-entry fobs, can support entry or starting while a compatible fob is nearby. Available functions, detection range, and walk-away behavior depend on the vehicle and its settings.
Mobile Locksmith Pros offers proximity-key replacement and programming when the vehicle-specific system is supported. Call with the vehicle details and working-key status so compatibility and the required work can be confirmed.
How Proximity Keys Work
Radio Frequency (RF) Technology
A compatible vehicle may detect the fob nearby and permit entry according to its settings. Detection range and automatic-unlock behavior vary by vehicle.
Push-Button Start
Compatible systems can authorize starting while the fob is detected inside the vehicle. The starting procedure and supported functions vary by vehicle.
Automatic Locking
Some vehicles support walk-away locking when enabled. Check the vehicle settings and manual because this behavior is not available on every system.
Emergency Key Inside
Many proximity fobs include an emergency key blade, but the location and emergency procedure vary. Check the vehicle and fob documentation.
Information Needed to Check Compatibility
Vehicle details
Have the year, make, model, and VIN when available. Vehicles from the same brand can use different key systems.
Existing fob
Share the identifier printed on the existing fob when available and describe which buttons or functions still work.
Working-key status
Say whether a working key or fob remains. All-keys-lost requests may require a different vehicle-specific procedure.
When Do You Need Proximity Key Service?
Lost Your Smart Key
If a proximity key is lost, replacement and programming options depend on the vehicle-specific system and whether another working key remains.
Solution: New proximity key programmed
Dead Battery
Battery life varies by fob and use. A weak battery can affect remote operation for keyless entry. Check the vehicle documentation for its emergency-entry and starting procedure.
Solution: Battery replacement or new key
Key Not Detected
If your vehicle says "key not detected" or the keyless entry stops working, the key may need reprogramming or the vehicle's receiver may need repair.
Solution: Key reprogramming or system repair
Need a Spare
A compatible spare can provide another option if the primary fob is lost or damaged. The vehicle determines how additional keys are enrolled and how many it supports.
Solution: Additional proximity key programmed

Proximity Key Questions
How long does proximity-key programming take?
Requirements depend on the vehicle-specific system. The technician checks the functions supported by that vehicle after programming.
What if no working key remains?
An all-keys-lost request may require a different procedure from adding a spare. Call with the vehicle details so availability, required access, and the quote can be confirmed.
What if the fob battery dies?
Check the vehicle documentation for its emergency-entry and starting procedure. Many fobs include an emergency blade, but the procedure and available service depend on the vehicle and fob.
Will existing keys remain active?
Whether existing keys remain active and how many fobs can be enrolled depend on the vehicle-specific system and requested programming procedure.
