Keyless entry is a vehicle feature that allows drivers to unlock and sometimes start their car without using a traditional metal key. Instead, the system uses a remote transmitter or smart fob that communicates wirelessly with the car’s locking and ignition systems. This technology offers both convenience and security, reducing the need to fumble for keys and making it harder for thieves to gain access.
For Austin drivers, keyless entry is now standard on many makes and models, from economy cars to luxury SUVs. As a local locksmith company, we assist customers who have lost their keyless fobs, need a duplicate, or require ignition repair. We also handle reprogramming and replacing faulty keyless systems, ensuring you can get back on the road quickly and securely.

Types of Keyless Entry (Remote vs. Proximity)
There are two main types of keyless entry systems: remote and proximity. Remote keyless entry systems use a handheld remote or fob to lock and unlock the car at the push of a button. The signal is transmitted over a short distance, typically within 30 to 60 feet.
Proximity keyless entry systems, also known as smart key systems, automatically unlock the doors when you are near the vehicle with the key fob in your pocket or bag. Many also allow push-button starting without inserting a key. In Austin, many newer vehicles use proximity systems for added convenience and security.
How Keyless Entry Works
Keyless entry relies on radio frequency identification (RFID) technology. The car’s receiver constantly scans for a coded signal from your fob. When it detects the correct signal, it triggers the locking or unlocking mechanism. Proximity systems go a step further by detecting movement toward the vehicle, unlocking the doors automatically.
This secure coded communication ensures that only the correct key fob can unlock or start the car, preventing unauthorized access even if the mechanical locks are tampered with.
Benefits of Keyless Entry
The main advantage is convenience. You can unlock your car without physically inserting a key, which is especially helpful in bad weather or when your hands are full. Proximity systems offer even greater ease by unlocking automatically as you approach.
Security is another major benefit. Keyless entry systems use encrypted signals that are difficult for thieves to replicate. Many also integrate with transponder key technology and vehicle immobilizers for added protection.
Which Vehicles Have Keyless Entry?
Most modern vehicles come standard with some form of keyless entry. Remote systems are common on cars built after the early 2000s, while proximity smart key systems are found on many mid-range and high-end models from the last decade.
If you are unsure whether your vehicle has keyless entry, check your owner’s manual, contact a dealer, or ask a professional locksmith. In Austin, we service a wide variety of makes and models, from compact sedans to luxury SUVs.
Common Issues with Keyless Entry
Keyless entry problems often involve a dead or weak battery in the fob, damaged internal circuits, or interference from other electronic devices. In some cases, the issue lies in the vehicle’s receiver module rather than the key fob itself.
We provide troubleshooting and repair services in Austin, including battery replacement, circuit board repairs, and mobile programming for new or replacement key fobs.
Keyless Entry Replacement and Duplication
Replacing a lost or damaged keyless entry fob requires both cutting a compatible key blade (if applicable) and programming the fob to match your vehicle. We handle key cutting and programming on-site for most makes and models in Austin.
If you want a spare fob, we offer quick and affordable duplication services. Having a backup fob is the best way to avoid being stranded if your primary fob is lost or fails unexpectedly.
