Keyless entry systems have changed the way we interact with our vehicles. Instead of inserting a physical key, you can now unlock your car remotely or simply walk up to it with the key in your pocket. This convenience has made keyless systems increasingly popular among Austin drivers. Whether you own a newer push-start SUV or a sedan with basic remote entry, knowing how your keyless entry works can help you when you lose your key, need a duplicate, or face a lockout emergency.
At Austin Key Replacement, we specialize in helping you understand, duplicate, and replace keyless entry systems. If you're locked out, need an ignition repair, or want a backup key cut and programmed, we bring everything to your location. Our Mobile Automotive Locksmith Services are available all across Austin and the surrounding areas. We also explain how these systems work and what to do when they fail—right here on this page.

There are two primary types of keyless entry systems: remote entry and proximity entry. Remote keyless entry uses a key fob with buttons that allow you to lock, unlock, or open the trunk from a short distance. These are the most common and typically found in vehicles from the early 2000s and up.
Proximity keyless entry, on the other hand, doesn’t require pressing buttons. As long as the fob is within range, the car will unlock when you touch the handle and may even allow push-button start. For a deeper explanation, visit our article on What Is Proximity Keyless Entry. Knowing which type your vehicle uses helps when requesting a duplicate or replacement.
Keyless entry systems rely on radio signals between the key fob and the vehicle. When you press a button or get close enough, the fob sends an encrypted code that matches the vehicle’s internal system. Once authenticated, the doors unlock and some vehicles even enable push-to-start ignition.
Many systems use the same technology as transponder keys. Learn more by checking our article on What Is Transponder Key?.
The biggest benefit of keyless entry is convenience. You can unlock your car without digging for keys or fumbling in the dark. It also allows for quick entry during emergencies. Some systems let you unlock just the driver door for added security.
Modern keyless entry systems are also more secure. They use rolling codes to prevent signal copying. Many keys also integrate with alarm systems and trunk access, giving you more functionality in a compact device. To see how this compares to other systems, read our piece on What Is a FOBIC Key.
Keyless entry is now standard on most mid-range and luxury vehicles from 2010 onward. Brands like Toyota, Honda, Nissan, Ford, and Chevrolet use both remote and proximity versions. Higher-end models from BMW, Audi, and Lexus tend to offer advanced proximity systems by default.
Many Chrysler, Dodge, and Jeep vehicles also use unique systems like FOBIK keys. For help identifying your specific key type, our team can use your VIN Number to determine the exact match. You can also visit Find a Car Dealer for OEM options, or contact our locksmiths for mobile help.
Battery failure in the fob is the most common issue. This can lead to the car not unlocking or the engine not starting. Damaged fobs or worn buttons are also frequent problems. Sometimes, the receiver module inside the car fails, requiring diagnosis and reprogramming.
If your vehicle won’t start or recognize the key, our Ignition Repair And Replacement Services can help. If you’re locked out, use our Unlock Car Door Service to regain access without damage.
Replacing or duplicating a keyless entry system requires both key cutting and electronic programming. You can order blanks from services like Where To Get Cut Keys Online and have them programmed by a locksmith. Programming tools vary by vehicle and not all models support DIY methods.
Our Car Key Duplication Guide explains everything you need to know about remote and proximity duplicates. If you've lost all keys, see Lost Car Keys! What To Do? for step-by-step help.
