2000 Toyota Camry CE With Factory Anti-Theft, CompuStar CS4900S

Hi all, I have 2000 Camry CE with a factory Toyota security system installed, has the red led with what looks like a mic on a knockout piece in Dash left side of steering wheel. It has a regular all metal key, no chip. I bought a CompuStar CS4900S Remote start/keyless entry kit that I'd like to install on my car. Is there a way to install this remote kit while still being able to use the factory anti theft system in conjuction with this kit? What I would like to accomplish is basically to be able to arm the factory system when i use the remote to lock the doors and disarm factory system when unlocking using the remote. On top of being able to remote start the car. Hope I'm making sense. Thanks in advance guys! B2000 Toyota Camry

I think you are talking about two things., Factory Alarm system and a Factory Transponder system in the ignition switch. If you can use a plain metal key from them hardware store to start the car it does not have a transponder based ignition immobilizer system. While I don't remember seeing any Camry CE's with a Factory Alarm system you could test to see if your car has it. Just remain in the drivers seat when to park the car and turn off the ignition. Remove the key and open the drivers door. While the door is open, press the power Lock button and then pull the door closed. Wait for >90 seconds and then open the drivers door with the inside handle. If you have the Factory Alarm system the horn will start honking. Your car probably has niether system so that little light is just there to look like some type of security system. Test to see how it comes on and goes off before installing the after market R/S. It might be via the ignition switch or the lock / unlock switches.Soldering is fun!

Hi kreg, Thank you for your reply. I did try out what you said: sit in car, open door, lock the car using the door lock, close door, wait about a minute or so. The light stayed on solid for a few sec then stared flashing on and off...I then opened the door from the inside and it started honking the horn. So, I definitely have a factory alarm installed. This car used to have a factory door lock/unlock remote but my brother lost it. Not that it matters now since I am trying to add this CompuStar system on it. So do you think I could literally just hook up the CompuStar remote door lock wire as normal to the door lock wire on the car harness since it seems like that should arm the factory alarm system as well? Thanks B2000 Toyota Camry

I don't do a lot of older Toyotas, but can you arm and disarm the system using the key in the drivers door ? If so there should be 2 wires coming from the key cylinder one to arm and one to disarmIf i Can't Install it    I Don't need it   Joe

In the lower Driver Kick Panel there is a 20 Pin connector. It has the two wires you are looking for. Info below : Lock / Arm = Blue/White wire at Pin 4 Unlock / Disarm = Red/Green at Pin 3 They require a (-) pulse from the Compustar. As mentioned by Chev104275, these are the Drivers Door key cylinder wires. Also, being as your car has a Factory Alarm system you should apply (-) GWR to the cars' Keysense wire to prevent the alarm going off with a R/S. KEYSENSE (-) BLUE/BLACK in 2 Pin plug by ignition switch on steering column.Soldering is fun!

Thanks for both of you guys' input chev and kreg. So could you guys check this wiring diagram of the CompuStar CM900 Module I have. There are some things that I am still confused about. The ones I have question marks are what I'm not sure. The ones I left BLANK are the ones I'm not sure what wire too hook it up to. I am not sure how to proceed with what you are recommending of applying (-) GWR to the keysense wire. First of all, would you explain what GWR means? Does that mean "ground wire"? Can I just hook up one of the CompuStar output wire like the (-) Status output pin 4 on the CN3(Gray) to temporarily apply (-) to keysense while i remote start it without me being inside the car yet? Note that I did use the remote color wiring information found here at the12v.com as well as a wiring diagram that I pulled from my ALLDATA. EDIT: Just realized that the labels I made on the picture is too small to be able to read after being uploaded. So I'll just type it out below. Please do correct me where I'm wrong in my wiring, and like I said, BLANK/EMPTY means I'm confused how to wire - so assistance is greatly appreciated and needed.

Thank you for this Kreg! I am still wrapping my head around all the info you provided me. I am still trying to understand for myself so I can get the theory down, the path of how it works so I could apply it this to different projects I may have in the future that I might want to install a R/S module. I might have to print out the Wiring Diagram from ALLDATA so I could follow the wiring to better visualize it for me so I could understand the electrical path. I truly appreciate all the help with the wiring and all the information!2000 Toyota Camry

Back and need assistance again, Could you point me in the direction of where this Black/Orange Acc wire would be located to tap my engine sensing input wire into? Also, does this module only need to get tapped into the starter(red) and not need for that red wire to be physically cut? Just curious cuz I've seen some R/S modules that physically cut the 12v starter(red) wire from the ignition connector and then the 2 cut ends gets connected to 2 thick wires individually....(I'm pretty sure it's an internal relay) If everything is just tapping and no cutting with this kit then this is great as i like to leave the harness intact(mostly besides from some tapping of wires...)2000 Toyota Camry

Sorry for the late reply, on vacation... The Tach wire is sometimes found at OBD2 plug, Pin 9. Otherwise use a F.I. or Spark Coil wire. The CM900s does not provide Starter Kill/Anti-Grind directly with an internal relay. You could use an external SPDT 30 Amp Relay and a signal from the R/S to do this function, cutting the vehicles Starter wire.Soldering is fun!
