2005 Volvo XC90, Remote Start

Hi everyone,

I am installing an Avital 4113 R/S in my 2005 Volvo XC90 and know that I need a key bypass unit.  However, I don't like the idea of leaving a spare key inside a 556UW or any other like it.  I've heard about the Fortin units but is it true that some of the units are keyless?  Like the EVO-ALL or EVO-CAN models?  I've done quite a bit of surfing the web for answers but none convinces me.  This is my second install (first was on my 1991 Nissan Maxima GXE). Once and for all what keyless unit can I use.  If there is none then what is an adequate unit I can use with my system?

Thanks to everyone...

Most newer units are keyless, but you are not gonna find one for that vehicle. You are gonna have to lose a key.

I am hooking up a  Ready Remote 24921 to a 2005 Volvo XC90. My r/s hook to the vehicle will be pretty much simple;  ignition wires, ground, brake and door locks only. I don't need all the other accessories connected.  I pretty much figured out how to hook up the r/s to the vehicle ignition wires but could not figure out where to hook up the TBXKEY wires to the R/S.

Is there anything else I need to know as far as the r/s hook up to the vehicle? 

Thanks in advance...

On the TBXKEY European installation it says to cut the wires for a better hook-up.  I've located the factory transponder ring with the green connector (r/h side of steering column) with about six wires. Which wires do I cut and connected to the TBXKEY?  

I have not tried the traditional way (placing the loop over the transponder ring) but I've read problems so I wanted to go the best way... 

Thanks again!

I finished the install of the  Ready Remote 24921 to my 2005 XC90 but unfortunately triggered the SRS light. I did not hook up the BLUE wire like other forums did. I did not know what caused it. Should I have hooked it as ACCESS2?

On the other hand, it would only start with the key in the ignition. I have a TBXKEY (replacement for 556U) for the immobilizer but I think the antenna loop does not work well. I wrapped it around the immobilizer but no luck.

I hooked up the Violet wire of the TBXKEY to the Yellow (keysense) on the vehicle. Do I have to splice this into the IGN2 as well? Can I splice the loop antenna wire into the cylinder? Which color wires are they? There are 6 wires that connect below the ignition cylinder immobilizer.  I do not have the lock/unlock hooked up...does this matter?

Thanks again

Hook up all accesory and ignition wires and see if the error on the srs goes away with the r/s/

You don't have to connect the keysense wire to the ign2 wire. No you can't splice the loop into the cylinder, i don't think you have to cut any of the factory wires, someone else will have to verify this one.

I'm not really concerned with the SRS right now.  Most likely a dealer reset. 

Is there "right side up"  when placing the key inside the TBXKEY?  Do I have to hook up both Standard and Advance methods?  I have the Standard hook up right now but it still would only start with the key in the ignition.   How about making more than one loop around the ignition cylinder.  All signs lead to the immobilizer system.  I'm stumped??????? 

Thanks everyone...

I finally got the R/S to work.  Surprisingly, I only have one loop over the ignition cylinder.  Once got it to start, I glued it in place and put back the covers...worked like a champ. I'm happy now except for the SRS light. 

I only have the ground, power and status output hooked up on the TBXKEY.  The keysense was hooked up to IGN2.  One thing though, I tried to add more loops by splicing more copper wire but did not work.  It was bare without the insulation around the loops.  So, I took another antenna loop from my extra TBXKEY and used it...no mods.  It worked?  Hummm?

Does the loop have to be insulated?  You would think bare wires would generate more signal to the immobilizer but I guess not.  I'll insulate this one and use it for my other install...2001 Chrysler Sebring.

Thanks for the help everyone...

no defintely the wires should be insulated, specially since the the cyclender in metal....makes a big difference.
