How do I find out if my car is ready for a keyless entry?

[Jon K]

I have a 9/91 525, but its a 92 model year. I am not sure whether or not it will be ready for keyless entry. I am looking at this:

http://bmwalarm.vstore.ca/product_in...products_id/64

and says "This is a complete plug-n-play keyless entry system built for your pre-wired** E34 5-Series BMW (1992-1996)"

But I am not sure what's up or how to know for sure. Any help?

well you should have a prewired connector under the rear seat to the right of the battery, it might be tucked under some padding so dig around. black 12 pin connector, there is also a 1pin plug that is your hood pin. This should plug right in, if not the wiring is easy.

They sell junk and very little tech support. I'm still trying to get the rest of my refund. It didn't work in a '93 525i E34.

Jon,

Nice write up from a cardomain site on keyless entry in a 95 525 touring. Pics and all. Maybe it will help.

if you don't have that unit you can wire into the lock/unlock wires in behind the left front sub woofer

having said that if you do it this way there are issues with deadbolting the door

I dont mean to steal your thread JonK, but while we are on the subject, would there be any way to install a keyless entry system on my car without a very costly or difficult retrofit?

I drew up wiring diagrams for it as well. I use the 2nd channel to deadbolt and rollup windows You just need some simple diodes to make sure current doesn't travel the wrong way.

I have the wiring diagram drawn up for your reference if you need it
