Keyless entry and alarm, 2002 Chevy Impala

Hello all, I am looking to get all the information I need in one spot. I have tried jumping around the site reading different forums but get lost really quick. I am looking to install a keyless entry with a alarm on a 2002 chevy impala base. I am not interested in installing a remote start so if that takes out a few steps then it's a plus. Also, what systems would y'all recommend?

Viper 211HV Avital - 2101L those would be the quality but costly ~65 CM800S keyless entry and remote start. You can leave the remote start portion disconnected. ~65 as well or any cheap ebay no name brand keyless will do as well. After-all, its only keyless entry. ~30 Tons of brands, pick whatever fits your budget. Ted

Thank you guys! One question I have is that I have seen the other posts that say I need a 480 ohm resistor on the lock side with a relay system. The problem I am facing is that I cannot find a 480 resistor. will I need to combine a 10 ohm and 470 ohm? Also, does it matter if it is a 1/4 or 1/2 watt resistor?

1/4 watt is fine, 470R will do. If you buy a cheaper unit with only 2 lock/unlock wires you'll need a DEI 451 relay to drive or overcome the resistor. This comes with a wide selection of resistors. If the lock wires are 6 that means internal relays, you only need the resistor.

Howie, What do you mean only 2 lock/unlock wires? For example using the Compustar CS700-A is this one that would need a DEI 451m relay? As for the DEI 451m relay is it the same as wiring two relays together? I have a diagram showing how to do this and was planning on using two relays, would the 451m make it easier? Sorry for all of the questions I just want to absorb everything I can. Thank you for everything!

Yes you can use 2 relays, the 451 plugs directly into DEI product, not sure about Compustar, also smaller size, plus the resistors, as an installer I much prefer that to two separate relays, except if the unlock is a direct NEG switching you'll only the relay on the lock side.

This is the diagram that I have. From what you said I guess that I would only need one relay?

UPDATE So I went with the Avital 3100. I am looking at the wiring and trying to correspond it over to my vehicle but a few are not clicking for me.
