Hi, got a 98 Accord EX three months ago. It has the keyless imm. security
system. I don't want to disable the system and would like to use the same
remote. What can I add for security?
I would like to add a shock sensor and siren, for all the kids that play outside that bang into my car.. an ideas...

 

I think as long as the shock sensor output is a ground or 12 volts, you can add it to your oem security. Are you sure it doesn't have one already? Do you have an alarm, or is it a keyless entry only? Anyway, if it is an alarm, you can wire up the shock sensor and have it trigger a relay (if it outputs 12 volts). If its output is ground, just hook it in parallel to the door switch.

 

if i remember correctly the stock honda security systems come with manuals u can refer 2 for opt. add ons.

 

I couldn't find any info into the manual.
I will check again.

 

DEI, the make of Viper&Clifford alarms have a line call "Automate", use for New Cars. They interface with you stock alarm, by adding a dual stage shock sensor, starter kill, but it stills allow you to use the factory remote.
