When purchasing the bypass module for the compustar alarm, do I get the DEI 555I or 555H? They say the 555I is for the Civic and RSX while they dont list anything for the 555H. So which one is the right one for the S? Thanks fellas!

 

right unit for the s is 556u.
and YES you need the key inside the module.

 

Can anyone verify this?

Also, is there a bypass module out there that does not require the use of a spare key?

 

not yet for the s2000.
i just did remote start on s 2 weeks ago.
