Proximity Keys / Smart Keys
Starting at $150 - $300
Proximity keys (also called smart keys) are advanced keyless entry systems that unlock your vehicle when you approach and lock when you walk away. No button pressing needed - just keep the key in your pocket or purse and the car detects it automatically.
Mobile Locksmith Pros programs and replaces proximity keys for all modern vehicles throughout El Paso, TX. These sophisticated keys require specialized programming equipment and expertise - we have both and can handle all makes and models.
How Proximity Keys Work
📡 Radio Frequency (RF) Technology
Proximity keys use low-frequency radio signals to communicate with your vehicle. When you're within range (typically 3-6 feet), the car detects the key and automatically unlocks.
🚗 Push-Button Start
Most proximity keys work with push-button start systems. Just keep the key in your pocket, press the start button, and the engine starts. No key insertion needed.
🔒 Automatic Locking
Walk away from your vehicle and it automatically locks. The system detects when you're out of range and secures the doors for you.
🔑 Emergency Key Inside
Every proximity key has a physical key blade hidden inside for emergency access if the battery dies or the system malfunctions.

Proximity Key Questions
How long does proximity key programming take?
Proximity key programming takes 30-60 minutes. These advanced keys require more complex programming than basic fobs, including system calibration and range testing. We work efficiently while ensuring everything works perfectly.
Can you program a proximity key if I don't have any working keys?
Yes, but it's more complex. We can program proximity keys even without working keys, but it requires accessing the vehicle's computer system directly. This may take longer and cost slightly more, but it's still doable on-site.
What if my proximity key battery dies?
If the battery dies, you can still use the emergency key blade hidden inside the fob to unlock and start the vehicle. We can replace the battery for $10-$20, or if the key is damaged, we can program a new one.
Will a new proximity key work with my existing keys?
Yes! New proximity keys are programmed to work with your vehicle's existing key system. Your old keys will still work, and the new key will work alongside them. You can have multiple proximity keys for the same vehicle.
