Locksmith explained
Investing in a professional security system installation is no longer optional for most owners. A robust setup combines physical deterrents like deadlocks with electronic safeguards like Thatcham-approved alarms and GPS trackers to ensure your van stays where you parked it.
Prices vary depending on whether you are fitting a single deadlock or a comprehensive "Gold Standard" security suite. All prices below include professional installation and VAT.
| Item | Low £ | High £ | Notes |
|---|---|---|---|
| Single Deadlock/Slamlock | £150 | £280 | Per door, including high-security cylinders. |
| Thatcham Cat 1 Alarm | £350 | £650 | Full perimeter and interior protection. |
| GPS Tracker (S7 Rated) | £200 | £450 | May require an annual subscription fee. |
| OBD Port Protector | £80 | £160 | Prevents "key cloning" via the diagnostic port. |
| Full Security Package | £750 | £1,500+ | Multiple locks, alarm, and tracker bundle. |
The primary cost drivers are the Thatcham Category rating of the hardware and the number of doors requiring physical reinforcement. Higher-spec trackers often involve a lower upfront cost but require a monthly or annual monitoring fee.
While DIY kits are available, professional installation is strongly recommended for van security. Most UK insurance providers require "Thatcham-approved" equipment installed by a certified technician to validly lower premiums or honour theft claims.
Improperly installed locks can lead to "door skin" rust within months, while amateur wiring of alarms can interfere with the van's ECU, potentially voiding the manufacturer's warranty.
Generally, no, provided they are fitted by a professional. However, any electrical issues caused by a poorly installed alarm may not be covered under the manufacturer's warranty.
A deadlock requires a key to lock and unlock, giving you control. A slamlock automatically locks the door as soon as it is shut, which is ideal for multi-drop delivery drivers.
An alarm deters a thief, but a tracker helps recover the vehicle if they manage to tow it or bypass the electronics. Many insurers now insist on both for high-value Transits.
It is a physical or electronic device that stops thieves from plugging into your van’s computer to program a new key, a common method for stealing Transits without the original key.
Yes, professional locksmiths can "key alike" all the additional security locks on your van so you only need to carry one extra key for the side and rear doors.
