Might factory alarm mean factory keyless entry?

[Paul Bennett]

Before I get carried away doing something needlessly...(again)

My new-to-me 1993 190e has a alarm sticker on the rear windows for radio and ?? Might this mean a factory keyless entry was provided but lost by subsequent owners?

If all I need to do is check the VIN with the dealer to purchase a KE FOB, I will cancel plans to purchase an aftermarket keyless entry. OTOH if the silly alarm was only intended to discourage radio theft, I'll go ahead with the DIY KE project.

Thanks for any insight and guidance.
