Ebay Keyless entry

Post by Mar55s » Sat 12 Jan, 2019 9:54 pm

:sign2:

Hi all!,
Well this is more a shot in the dark than anything else, maybe one of you out there has the answer I'm looking for.

I recently purchased a SEC500 and I feel as if I'm rescuing it more than simply enjoying it, so far I've replaced injectors, fixed the suspension, etc. and i realize that this is a long term project but overall, the car is in great shape. When i got it, the central locking wasn't working but it was due to a hose in the boot that had come off its connector so that felt like i scored! :laughing6:
It is at this point that decided i wanted to be able to lock and unlock the car remotely. I bought one of those keyless thingies but for the life of me, i can't figure out how to connect it... i've followed instructions best way i could but it's translated from chinese sooo... :Doh:

If anyone has installed one of these, could you tell me how you did it???

Thanks in advance!
(This is it)

what sort is it? One that sends an electronic signal to the pump or one with a solenoid that operates the switch in the drivers door?

The one that drives the motorised actuators can be wired to relays (some may be able to wire directly) to activate the switches in the door/boot or wherever the key can centrally (un)lock.

You should be able to splice onto wires directly on the pump in the boot

If you asked all these questions it may be that your electrical understanding may need a bit of refresher... and probably simpler to have an electronic (or auto electric) shop help you.

This is the set up i bought because it works, supposedly, with pneumatic systems.

I did the alarm-immobiliser on my car and later modified it for additional vac pump operation (107 with Vacuum used for both lock and unlock). This is not quite like your system but similar.
However, I got several C/L pumps from 126 which are vac/pressure (as a replacement for my VW golf cruise control vac pump in the boot) and I well researched the ways to use it as my current setup is noisy.

The 'pneumatic' setting switch sends 5 second lock or unlock commands instead of the 1 sec for electromechanic actuator type.
The splice required is to imitate contacts as made by the switch behind the key in the boot or in the door. I cannot remember if these were shorting lock or unlock wire to GND or to +B.
Your C/L control seems to have NO/NC relayed output hence it should do easily either way. Actually it looks quite a decent model.

I will not be able to tell you which wires to splice and where without looking in the car.
