Pajero Owners Club of South Africa

Hiya

I retrofitted keyless entry to my Gen3 a week ago. I have a 2001 DiD and it was annoying missing keyless entry. What a pain not having that.

I'm on the Autostyle mailing list and received a mailshot a while back. They were selling central locking kits for R150. Ridiculous pricing, they're still selling them at R250. I ordered not expecting the quality to be good, but it was surprisingly impressive. I was looking for a keyfob that looked automotive in design (I could have fitted a regular house one) and that had two separate buttons for locking and unlocking. The Autostyle fitted the bill. I went over the electronics and checked those too. The build seems reasonable, unfortunately the chipset isn't rolling code, rather it seems to be a binary type with half a million different combinations. Not as secure as I'd like then, but putting a brick through a window is immensely easier than capturing a keyfob.

I only wanted the keyfob and receiver. Solenoids were discarded for this project. My Pajero didn't have keyless entry, but it did have central locking, I didn't want to mess with that.

The set came with solenoid and therefore the receiver was designed to switch positive on the solenoids. I modified the board by removing a couple of components and converted it to switching negative which is what the Pajero needs. There are two central locking signal wires on the white connector block just under the dash next to the front passenger door. I tapped into those wires to provide the signals to lock and unlock the doors.

You need a power source too, obviously. I installed by DC-DC charger at the same time and used the same power source for powering both the central locking and charger.

If anyone wants more detail, I'm happy to supply.

Works like a treat now, I'm really happy with the setup.

nice work!

I'm not nearly smart enough to fiddle with circuit boards

Hi Marius

Haha, I'm an amateur at electronics, it takes plenty of hours of staring at circuit boards before the purpose starts becoming clear. In this case there was a "feedback" circuit on the output of the relay which in turn cuts off supply to the relay again. This is to ensure that the door lock solenoids were only active for the appropriately short amount of time. Given that I wanted to switch negative and not positive I had to drop all of that circuitry. Now the relay stays active as long as the button is pressed, but that's okay because the Pajero has it's own timed relays.

Be careful, I had a problem with my VW bakkie once where the battery on the remote went flat. There is no point in phoning a locksmith... To many of these Autostyle modifications is rubbish. Believe me I had allot of them screwed on to my bakkie.

Hi Jaco

Thanks for the heads-up, but that's specifically why I didn't want to put in a full-blown alarm system with central locking replacement. I'm quite happy with the Pajero the way it is and didn't want to touch any of the wiring unnecessarily. As it stands I only tap into (I didn't even cut them, just separate the insulation) two signal wires. These are the signal wires that run from the door locks which signal the rest of the vehicle's locks to open and close.

It's not an alarm system in any way, if the battery goes flat I can still open the car as per normal with the key.
