I purchased a Keyless Entry (model Lb-405.mfg by Lanbo)..typical made in China...supposedly easy to install. The pneumatic central locking vacuum is in the boot. I'm wondering if anyone has had any experience installing that and can enlight me as to which of the wires in the vacuum are attached to the keyless unit.
My car is a 1987 420 SEL (purchased new in La Jolla California in September 1987..current mileage is 122,300 miles) .
The Beast, as I call it is never driven in rain or snow and with this covid-19 I'm killing/spending time hoping to do this supposedly easy upgrade.
I welcome any advice.

Stay safe & healthy and have a blessed day.

The round plug on the pump is what actives the lock/unlock, but, it operates a little like a house light where there are two switches for the same light, so there isn't an "un-lock" and a "lock" wire

With all the issues of cars being stolen via keyless entry I wouldn't bother. Do you know how good the security is on the equipment? My sisters Fiesta was stolen that way off her drive.

Hello and welcome......

I know everyone has differing ideas, but I cannot think of one good reason to do what you are wanting to do - not one....???

But good luck anyway - I have a feeling you're going to need it.

Thank you Bill for the advice.....I'm having 2nd thoughts about the convenience of not inserting my key in the door.
Stay safe and healthy.

He's talking about installing remote central locking, that's all, not keyless go (that would be some undertaking!) so there won't be any greater risk of the car being stolen

You are correct..the remote project is to lock/unlock the doors utilizing the existing central locking system. (There is no way i would consider keyless go at all.)

Stay safe and healthy.

The title Remote Central Locking would have been more helpful. Keyless Entry by definition is entry without a key?

Without using a key (in the locks).
Keyless-go still has a key, you just don't even have to press the button.

That's true...so many different ways to describe so many different choices.

After all is said and done I took the advice of a few of the Forum Members and decided to abandon the idea rather than feed my boredom with this project and the caras is instead.
