You are protected by the L4V Van Alarm, the only Thatcham certified aftermarket alarm dedicated to the LCV market. The L4V Van Alarm is programmed to interact seamlessly with your vehicle’s original remote and provides features that will add a new level of protection to the load area.
Activate your extended warranty
The alarm is programmed to use your vehicle's original remote. This means when you lock and unlock your doors, you will be arming and disarming the alarm at the same time.
Arming and disarming the alarm is signalled by an audible beep.
One beep for armed, two beeps for disarmed.
The system has a 30 second pre-arming period (arming delay) during which the LED is on steady. After 30 seconds, the LED will flash once per second to confirm the alarm is armed.
The alarm system can be armed without activating the internal sensors i.e, Wireless Infrared Sensors (PIR) (Load Area) or Ultrasonics (Cab Area) whilst keeping the exterior perimeter protected (Anti-Peel / Anti-Tamper Sensors and Movement Sensors).
Note: Sensor exclusion is bound to each single arming cycle.
This feature allows you to ascertain the reason why your alarm triggered, and what part of the vehicle caused it.
If you return to your vehicle and the alarm has triggered, the system will give five beeps and five flashes of the turn indicators on disarm (instead of the usual 2 beeps). This will indicate there has been an alarm trigger prior to disarming.
To identify the cause of the last alarm trigger, turn the ignition key “ON” and count the number of flashes of the red status LED installed on the dashboard. It will indicate the last alarm detected. Optical signals are repeated 3 times in a row. To interrupt, turn ignition key “OFF”.
The table below lists the various alarm causes and relative number of LED flashes:
2 - LED OFF - 2
Ignition attempt
10
3 - LED OFF - 3
Door opening
10
4 - LED OFF - 4
Bonnet opening
10
5 - LED OFF - 5
Boot opening
10
6 - LED OFF - 6
Ultrasonics
10
8 - LED OFF - 8
Wireless door contacts & movement sensors

9 - LED OFF - 9
Wireless infrared sensors (PIR)
10
Note: Once the ignition key has been turned off, it will clear the alarm memory. Make sure you have identified the cause before doing so.
Service mode is for ‘’emergency disarming of the alarm’’ or ‘’total disarming of the alarm’’. To enter service mode:
Note: It is extremely important you only do this in an emergency.
PIR sensors work by detecting infrared light given off by a moving object, or a person emitting heat. They are positioned to give maximum protection, ready to trigger the alarm if anybody enters the load area.
Locks 4 Vans have designed and manufactured vehicle-specific brackets for our electronic sensors, to reduce the risk of the common "Peel and steal" type attack (vehicle dependent).
When you lock your vehicle, it will arm the alarm and the LED receptacle will go solid red for 30 seconds (Arming period). After this period, the LED will flash once a second. This now means your alarm is fully armed.
All your perimeter is armed.
- Anti-peels sensors are armed after 30 seconds.
- PIR will be fully armed after 5 minutes.
- L4V Motion sensors for your Pickup canopies will be armed after 5 minutes.
After the alarm has been activated, disarm the alarm. You will receive 5 beeps to confirm the alarm was activated.
Open the door and turn the ignition on (lights on the dashboard, or as far as it will go before crank starting the engine).
The LED will flash in a sequence to determine the cause of the activation. It will flash the corresponding number 'pause' and continue 3 times in total. For example, 6 flashes is a ultrasonics (Cab).
For a graph list, please refer to the LED / Alarm Trigger see user guide for full breakdown.
The alarm system can be armed without activating the internal volumetric sensors (wireless infrared PIR or Ultrasonics), whilst keeping the exterior perimeter protected.
To do so, proceed as follows:
They all take batteries. To test the batteries are still working, you can check the following:
PIR: Press the button once on the PIR and the LED should come on for a short period of time. This means that your PIR is working and the batteries are ok. If not, you would need to replace the CR2032 batteries and test again.
Wireless Anti-Peels sensors: Bring the magnet close to the sensor and then move the magnet away from the sensor. You should notice a red LED light up as you pull the two apart. If it does, the sensor is working and the batteries are fine. If not, replace the batteries with CR2032’s and test again.
L4V Motion Sensor: Press the button on the center of the sensor, a green light should flash as you press the button. If not replace the batteries with CR2032’s and test again.
We advise you to periodically check and change your batteries. If this doesn’t work, then seek technical advice.
It is extremely important you use this very carefully.
It is either used as an emergency override (See user guide for full details).
Enter programming mode to either enable or disable alarm settings (Speak to an alarm technical advisor first). Both are to be used with caution.
If the ignition is off, there is nothing to be concerned about. Do not insert the electronic touch key while the ignition is on. This will enter programming mode and clear all the alarm settings.
You would need a technical advisor to talk you through re-programming them back in.
You will need to use your override touch key to temporarily disable the alarm until you can speak to a technician.
While the alarm is sounding insert your touch key into the receptacle, if accepted it will turn the alarm off. Full details are within the user guide.
If this doesn’t work, you may have a power issue to the alarm and you will need to seek technical advice.
DO NOT CUT THE WIRES TO THE LOAD AREA SIREN OR ENGINE BAY SIREN. THIS CAN HAVE SEVERE CONSEQUENCES TO THE ALARM MODULE, RESULTING IN PERMANENT DAMAGE AND VOIDING ANY WARRANTY.
Once your vehicle battery voltage drops below 9V, the alarm will sound to alert you there is not enough power. The siren will continue to sound for up to 18hrs (Depending on the charge in the sirens back up battery) or until power is re-applied.
The emergency override touch key would not turn the alarm off in this instance. To stop the alarm from continuously sounding, you would need to either jump start the vehicle, connect a battery charger or replace the battery.

Locks 4 Vans – Issued April 2023
During adverse weather conditions or high usage, it may be necessary to increase the maintenance frequency. An indication that lubrication is required is when key operation, including insertion into the cylinder becomes stiffer or more difficult than usual.
Shake L4V Lock Lubricant can vigorously for several seconds to ensure contents are mixed.
Insert the nozzle of the L4V Lock Lubricant into the lock's keyway and apply sufficient lubricant to penetrate the cylinder mechanism (approximately a 1 second burst).
Run the key in and out of the cylinder several times.
Apply a second short application of L4V Lock Lubricant.
