Vehicle theft from driveways, primarily through relay attacks on keyless entry systems, is a documented concern across the wealthier parts of Hertfordshire. The St Albans and Harpenden corridor, with its concentration of high-value vehicles on residential driveways, is a consistent target. A closed automated driveway gate is one of the most effective physical deterrents available, not because it is impossible to breach, but because it makes the property a significantly harder target than a neighbouring property without one.
Why Gates Deter Vehicle Theft
Relay theft relies on speed. The criminals need to approach the house closely enough to amplify the key fob signal, walk to the vehicle, start it, and drive away. A closed gate between the road and the vehicle forces a second obstacle into this chain: the gate itself must be passed before the vehicle can be reached, and the vehicle cannot be driven through a closed gate. The additional time, noise, and visibility involved in breaching or climbing a gate is often enough to redirect the attempt to an easier target.

Auto-Close and Timed Locking
Automatic closing after a set delay is a standard feature on all automated gate systems and should be enabled for any installation where security is a primary consideration. Most control boards allow the auto-close delay to be set between fifteen seconds and several minutes. The gate closes automatically after the delay whether the remote was used or the gate was opened by any other means. This removes the risk of leaving the gate open through forgetfulness.
Access Control That Adds Security Value
A video intercom with recording capability is the most security-relevant access control addition beyond basic remote controls. A camera at the gate records activity regardless of whether anyone answers, creating both a deterrent and an evidence source. Push notifications to a smartphone give real-time awareness of gate activity from anywhere. Activity logs from keypad and proximity reader systems show a timestamped record of every opening event.
Gate Construction and Physical Resistance
A heavy wrought iron or steel gate on reinforced posts offers more physical resistance than a lightweight aluminium gate on standard hinges. However, the primary security benefit of a residential gate in the Hertfordshire context is deterrence rather than physical resistance. A gate of 1.8 metres or above is significantly harder to scale and is the standard recommendation for security-priority installations. Most Hertfordshire planning authorities accept 1.8 metre gates under permitted development.
Insurance Benefits
Some vehicle insurers offer reduced premiums for vehicles kept behind a closed electric gate. The extent of any reduction varies by insurer and policy. Documenting the installation with photographs and commissioning certificates is worth doing if you intend to claim a security-related premium reduction. Check with your insurer before and after installation.
