I recently purchased a 1994 740i. It has a keyless entry system installed, but did not come with a remote. I purchased a remote, being careful to purchase one with the exact part number. There is a remote keyless-entry security system manual that came with the car, that explains how to program the remote. But the manaul does not say where to find the control unit, it only has a cryptic entry stating "the control unit is concealed within the vehicle". Can anyone tell me where the contol unit can be found. Also, if it is under the back seat with the battery, can anyone also tell me how to get the back seat out.
