Hey guys i just got done removing my central locking pump and found out its shattered to hell and back. I ordered the new central locking pump after i googled the part number on mine. Well now that i got the new lock pump i am wanting to buy a remote keyless entry FOB with the switch blade key. The key is uncut and it has the chip installed in it already. My main question is...How will i know for sure that the key will work for my car??? This is the keyless entry keyswitch i am getting. My car is a 1997 audi a4 quattro 2.8. Thanks guys!!!
