Just got a 1.6 astra envoy estate (2000/W), which does not appear to have central locking - if it is does have it it ain't working! Now - i'm finding this a bit of a pain, so was just looking for a couple of answers: a) can anyone tell me if my car is supposed to have central locking, or is there an easy way of finding out without ripping the doors apart? b) If it doesnt have central locking, does anyone have any experience with add on central locking kits? Are they straightforward to diy-install, or isn't it worth bothering with in the first place? cheers! ash
