GPS Jammers and Your Car Tracker
Jammers are a favourite tool of vehicle theft syndicates. Here is how they work and how to protect yourself.
Updated 26 September 2026 · TrackerPrices SA
Quick answer: A GPS jammer is a small device that blocks satellite and cellphone signals near it, so a GPS/GSM tracker cannot report its position. Using a jammer is illegal in South Africa, but criminals still use them, which is why jamming detection and radio-frequency backup matter.
How jammers are used in car theft
Thieves switch on a jammer during a hijacking or theft so the tracker cannot report the vehicle’s location, then move the car to a hiding place. Remote-jamming is also used in parking lots to stop central locking from working, leaving the car unlocked.
How trackers fight jamming
- Jamming detection: the unit notices it is being jammed and alerts the control room.
- VHF radio backup: radio-frequency recovery, such as Tracker’s network, keeps working when GPS and GSM are blocked.
- Early-warning alerts for unexpected movement or power disconnection.
Protect yourself
- After locking your car, check the doors are actually locked.
- Choose a tracker with jamming detection or radio backup if your car is high risk.
