The Toyota Hilux is currently the most stolen vehicle in New Zealand, The NZ Police data for the past six months put it clearly in the lead, so now is a good time for me to explain which models are most at risk and what security upgrades can be done.
According to the Police data, there were 176 recorded thefts of the Toyota Hilux from March to September 2025.
I crunched the numbers and found that 45 were actually Hilux Surfs, which knocks the total down to 131.
8th Generation Toyota Hilux (2015 – Present)
The current shape Hilux first appeared in 2015, it comes in a range of models and has had a couple of facelifts during its lifetime.
What security does the Gen 8 Hilux have?
- All models have a factory immobiliser.
- All versions with keyless proximity locking/push to start have a basic alarm (SR-5 and GR Spec)
- All post 2020 facelift models have a basic factory alarm – Note sold in NZ from 2021
What’s wrong with the factory Hilux alarm?
First off it disarms with the key in the door, so a forced entry via the door lock would defeat it.
The alarm only covers the doors and bonnet. There is no internal movement sensor in the cabin, let alone any provision to protect the load area should you add a canopy and keep gear in the back.
If the alarm does trigger it simply uses a security horn which is accessible in the engine bay.
If you have a canopy it is possible to add a PIR sensor to the factory alarm to cover the load area, but given the flaws in the original alarm, I recommend upgrading it at the same time.
Upgrading the Gen 8 Hilux alarm
I’ve noted that the ‘A pillar’ trims on the GR Hilux are black so have pre-painted ultrasonic sensors for the perfect OEM look.
7th Generation Toyota Hilux (2005-2014)
The 7th generation Toyota Hilux comes with a factory immobiliser as standard, but all models lack a factory alarm system.
If you’re lucky then you will already have the excellent Cobra AK4218 fitted which you’d be forgiven for thinking was a factory alarm. This was an option from new from Toyota NZ or myself. You’ll find the AK4218 user manual here.
Remote locking came as standard on all but some very early base specification models, (2005-2008) which also lacked central locking. My advice is to avoid these models if locking is important to you as retro fitting central locking is expensive on these.
Alarm options for the Gen 7 Hilux
The Vodafone Automotive 4822 is my recommendation. It can work in PLIP mode as a OEM upgrade alarm, so will work with the Hilux remote. It can be purchased with 2 new remote controls that should work out more cost effective then getting new remote keys from the Toyota dealership.
There are a number of different specs available depending on your budget and needs, plus if you wish to retain the Toyota remote or not.
The Gen 7 Hilux is reasonably simple electrically, so pretty much any after-market alarm is possible.
6th Generation Toyota Hilux (1997-2004)
The Gen 6 Toyota Hilux Security system in none existent. These did not come with an immobiliser, let alone an alarm system.
Most models got central locking as standard, but lacked keyless entry. Any models that do have keyless entry would have had the system retro fitted, either by the dealership or later in its life. There were some Toyota branded retrofit kits. Be ward, these do not include alarm or immobiliser functions.
The lack of a factory immobiliser makes these very vulnerable so I recommend getting that taken care of.
Security options for the Gen 6 Hilux
It’s worth considering an insurance grade alarm/immobiliser and having it control the existing remote locking
Good options include:
5th Generation Toyota Hilux (1988-1997)
Like the Gen 6 model, this lacks an immobiliser or alarm. Some models lack central locking too, but this can be retrofitted without any issues.
I’ve installed central locking to many of these Hilux models along with alarms and immobilisers.
Gen 5 Toyota Hilux security advice
Get an immobiliser as the bare minimum.
Toyota Hilux Security Considerations
Alarm Sirens
If you are using your Hilux off road, then I recommend making sure that your siren is waterproof. I recommend having a chat to me about how you’ll be using your Hilux before deciding on the best options.
There is no excuse for your installer to fit the siren so it can be easily ripped out of the engine bay. All generations have locations where a siren can be put out of reach.
Canopy Protection
If you have a Hilux with a canopy and keep gear in the load zone then I recommend adding a PIR sensor to your alarm.
Check out the full range of alarm sensors here.
Locking Canopy?
If the canopy unlocks with the doors, I can re-wire it so it only unlocks with the remote.
