02 V70 Alarm siren and alarm receiver with fobs

[soares71]

Looking for alarm siren ideally in good working condition part number 8637399.
Also looking for a fob receiver with 2 fobs for the same car I dont have part number for this but can look in case you believe to be for the same car.

if you are hoping this is a cheap option to get some keys working with your car it won't work , volvos security is much higher than the S/V40 which this method can work on .

no keys. Fobs only. Not even if i buy a receiver and fobs from the same car?

that's right the security is handled by the receiver , and the CEM all must match before unlocking is allowed . it gets more complicated with the key and starting ..

ok... didn't expect that. Any issues by having an aftermarket chinese one like this one? I read several reviews seems to work well in other cars. MY car siren is not working . the original alarm is not operating as well.

No that is no good , ok on a 20 year old car but not yours with a modern network electrical system .. why don't you just buy a new fob ?
