Keyless Entry Repeater: Full Information
What is a Keyless Repeater?
A car key repeater is a equipment that boosts the transmission from your vehicle remote. This system allows remote access to cars equipped with smart key technology.
Key signal repeaters are commonly used for authorized use such as automotive diagnostics and vulnerability analysis.
How Does a Key Signal Repeater Work?
The keyless repeater works by detecting the low-frequency signal from your car key and transmitting it to your vehicle. Here’s the mechanism:
- The keyless repeater detects the frequency from the key fob
- It amplifies the radio frequency
- The amplified signal is sent to the vehicle
- The automobile authenticates the key signature
- The car unlocks as if the remote were in proximity
