Need some help

[genphreak]

1) Did your car not come with keyless entry of any sort?

2) Is that (one pictured) your 'current' fob (for clarity, this one is clearly not for your model)

3) What are the differences internally between that fob and one that is designed for your module (assuming you have one)... examination of the chip used is of primary interest.

4) Are the module part numbers you list for late e34 (540)? If so, then the question is what is the difference in the connections for the module between the 540 production and the 530 (and the rest of the e34 models).

We must appreciate that over the long production of the e34 there were many advances in this field and they employed many different systems, (Infra red through to coded keys) so it is confusing for all of us as there are lots of solutions posted on the web that may (or may not) apply in each case. Further clarity on this subject generally is certainly necessary in the case of e31/32/34. Any similarities with e36 are important as this provides the comunity with a larger pool of more modern parts.

Perhaps posting a picture of what is under the back seat on your car would help- specifically the plugs that are there (opposite side to the battery). It would be worth removing the tamper-proof cover for clarity. Make sure the pics are good so people can see...
