Hi,

I have a 2nd Gen 93 es300 that doesn't have the factory keyless entry working anymore. I don't have the original key just a copy. My question is if its possible to use an aftermarket system with the factory alarm. I don't see the need for the extra wires and mounting the horn. Can anyone recommend a simple unlock/lock system to work with the alarm. Also could i just get one installed at best buy and have them skip installing the alarm. Thanks
