As featured in Land Rover World magazine and Land Rover Owner International magazines.

MUD UK are the exclusive distributors of the Land Rover Defender Meck Lock System®

Meck Lock System® protects by adopting the unique method of connecting to a vehicles hydraulic clutch circuit without altering any of the vehicle's original functions. By using a unidirectional valve activated by a security key, the passage of clutch fluid that operates the clutch mechanism can be securely immobilised. With the system activated, the clutch is locked in the open position securely isolating the drive between engine and gearbox.

Although a relatively new product to the Land Rover market, the Meck Lock System® is nothing new. The device was designed in Italy over 10 years ago and since then more than 160,000 installations have been made on all types of vehicles from cars to heavy plant machinery and trucks. So far, not a single claim has been made for a stolen vehicle fitted with the Meck Lock System®.

MUD were the first company in the UK to realise the Meck Lock System had the potential to offer a genuinely effective method of combating the increasing frequency of Land Rover thefts. Working with Meck Lock in Italy and Meck Lock’s UK importers, MUD have created an off the shelf Meck Lock System® suitable for DIY fitting to all Land Rover Defenders. Unlike notoriously unreliable electronic devices, the Meck Lock System® relies 100% on mechanical activation and immobilisation. The Meck Lock System® will happily cope with the most severe off-road environments including dust and sand, the thickest mud, deep water wading and regular power washing. With a complete absence of fragile electronics to go wrong, this makes the Meck Lock System® the ideal choice of immobiliser for expedition vehicles or vehicles working in remote environments.

The Meck Lock System® is activated by a multi patented key, designed and produced by just one company in the world. Keys cannot be reproduced and have more than 20 million different combinations. The anti-drill lock cylinder is made of hardened steel and has withstood prolonged independent laboratory attack tests completely intact. Three keys are supplied with each unit.

Another advantage of the Meck Lock System® is that it allows you securely immobilise the vehicle even with the engine running. This feature will be of special interest to those owners who work some distance from their vehicle but rely on the engine as a power source to operate ancillary equipment. i.e. winches, cherry-pickers etc.

Category 1 Thatcham approved immobilisers appear to offer little or no deterrent to the determined car thief. Likewise expensive Tracking devices A) won’t stop them taking your car in the first place and B) if you know how, can be very easily beaten. Fit the Meck Lock System® to your vehicle and leave it unattended safe in the knowledge that it’s protected by the most effective anti-theft device on the market.

A Land Rover Defender can be Meck Lock System® protected in around two hours and requires no specialist tools or training to carry out a home installation. Each kit comes with full instructions and everything needed to carry out a discrete and professional installation to your vehicle.

All of our DIY kits include made-to-measure pipework and fittings specific to the year and model of your Defender. When ordering, please remember to state which engine is fitted to your Defender.

Meck Lock System® FAQ

Where does the Meck Lock System® fit?

You can install the Meck Lock System® valve anywhere on your vehicle, however we recommend using the portion of the bulkhead behind the engine. On the majority of Land Rover Defenders, there is already a hole in the bulkhead, therefore no drilling is required.
This recommended mounting position offers a discreet, yet convenient location for the Meck Lock System® to be installed and operated from within the vehicle. Each system comes supplied with three keys.

How does it work?
By preventing the flow of hydraulic fluid to operate the clutch system, as soon as the thief attempts to drive away with your vehicle, the Meck Lock System® activates leaving the clutch system inoperative. When a thief attempts to drive off with the vehicle, they will suddenly find themselves with a 'dead' clutch pedal.. With the clutch system immobilised it is now impossible to drive the car away.

Can the device be bypassed?
The only way to beat the Meck Lock System® is for the would-be thief to bypass the Meck Lock System® under the bonnet. To do this, they would first have to arrive with a length of pipework, a selection of tools, a tin of clutch fluid and be prepared to waste valuable time bleeding the vehicles clutch system. That’s assuming they know your vehicle is protected by the Meck Lock System® in the first place. The stealth element of the Meck Lock System® means it's not until the thief attempts to drive the car away that they will realise something is wrong.

Can I fit the Meck Lock System® to another vehicle?
YES. Providing the vehicle is fitted with a hydraulically operated clutch system.

When I sell my vehicle can I remove the Meck Lock System®?
YES. We recommend you hang onto to the pipework you remove when fitting the device so that at a later date, should you wish, you easily can revert your vehicle back to standard using the original pipework.

How do I operate the Meck Lock System?
When parking your Land Rover, all you have to do is remove the security key. Removing the key from the lock, activates the device leaving your vehicle Meck Lock System® protected.

How much is it?
The Meck Lock System® fitting kit for the Land Rover Defender costs £410.00.

Can the device be fitted to my Discovery?
YES. The Discovery clutch system is identical to the Defender, however, due to the difficulty in routing pipework from under the bonnet into the Discovery interior this is a more difficult and involved job than the Defender installation. That and the lack of an obvious location to install the device within the Discovery meant coming up with a DIY kit was impossible. For Discovery applications we normally supply the Meck Lock System®  as valve only. Price to supply the Meck Lock valve only, minus the pipework is £390.00.

Can I fit the Meck Lock System® to the brakes?
NO… & YES!

EU law states that: "Devices to prevent unauthorised use preventing release of the brakes of the vehicles shall not be permitted." We are therefore unable to advertise or supply the Meck Lock System® for use as a brake immobiliser.

In Italy, fitting the Meck Lock System® to the brakes is commonplace. The Italians get around the EU ruling by claiming the system does not interfere with the braking system when in normal driving conditions. Only when the system is activated by the owner and the vehicle is at a standstill does it prevent the release of the brakes and these are not 'normal driving conditions.' Providing the braking system has not first been pressurised by the application of the brake pedal, then in a passive situation, the Meck Lock System® is not "preventing the release of the brakes". If a thief was to start a vehicle with the system activated they could theoretically drive away perfectly normally… until the first time they have to apply the brakes. As soon the brakes are applied, the Meck Lock System® would activate. When the vehicle had reached a standstill the brakes would not release making the vehicle impossible to drive away.

Although we go along with the Italians literal interpretation of the EU rule, we feel this is still a grey area and one that could be open to legal scrutiny. Therefore, MUD UK has agreed with Meck Lock System UK that we will not supply an off-the-shelf kit for fitting the device into the brake system. If we supply a Meck Lock System® to operate as a clutch lock and you plumb the device into your braking system, the purchaser does so entirely at their own risk. All warranties and guarantees will automatically become void.
