Car Alarm — UK Installation
Car alarm installation UK — combined with immobiliser
A car alarm alone deters opportunists but does nothing against relay attacks. Combined with a relay immobiliser, it closes both threat vectors. LockCar systems include alarm functionality as part of the complete security package.
The limitation of a standalone car alarm in 2026 is significant: relay attacks trigger no alarm and cause no visible damage. An alarm without an immobiliser is window dressing against the dominant theft method. An immobiliser without an alarm misses the deterrence layer. LockCar systems with motion alerts cover both.
LockCar alarm features
Motion detection alerts via app
IC3ST, IS357, and ONE Plus all include motion detection with instant app notifications. You’re alerted immediately if your vehicle is disturbed — even if no physical alarm sounds.
LockCar alarm features
Tamper detection
Alerts sent if the device itself is tampered with or if the vehicle’s electrical system is disturbed unexpectedly. You know before the thief succeeds.
