GSM Car Key Communication Device
The GSM Car Key is a compact quad-band GSM communication device supporting 850/900/1800/1900 MHz networks. It is compatible with supported GSM networks worldwide and requires a Micro SIM card.

Its built-in high-gain microphone captures sound from approximately 30–50 cm away, allowing even quiet speech to be heard clearly. The rechargeable battery provides up to four hours of talk time.

An internal indicator displays the device’s power and charging status. The indicator flashes while the battery is charging.

Important: The device must be switched ON while charging.

How It Works
Insert an active Micro SIM card and switch on the device. It will automatically answer incoming calls from authorised mobile phones or landlines. The integrated microphone allows the caller to hear sound from around the device, supporting convenient voice communication.

Important Warning
This product cannot open, lock or gain unauthorised access to any vehicle. It is strictly a GSM communication device and does not transmit signals that interfere with, copy or override a vehicle’s original remote-control frequencies.
