all of the 34's I have worked on had smartentry (as do s2 33's ) but not an immobilser system (or transponder setup as in the s14,14a,15) 14a had a full alarm that worked on entry only (that said I could add -and did- a shock sensor to the system )
would be interested to see the follows photos pls.

that will tell me for certain what you have
what model is your car? (34 obviously.) ECR34 or something else.
give me that info and I'll tell you what and if you have it. pretty certian you do not.
