OK, Tom, you can confirm the problem by pulling the driver's door panel and seeing where the fault is. My bet is that the lock link connecting from the back of the lock cylinder to the lock actuating mechanism broke. BTDT. (Must respectfully disagree with another poster who theorized this is a faulty pump. Doesn't fit the symptoms.) This is a VERY common problem, and the lock upgrade is in order if this is the fault. It would in fact turn the alarm on, as the alarm switch is mounted on the cylinder itself - but since the link broke, it would not activate the door lock. How to find out: pop the door panel off (20-minute job if you've never done it) and look WAY up in the corner where the door handle is. Have a helper turn the key. If you see the back end of the cylinder turn but the lock connecting mechanism running up the inside of the door doesn't move, then it's the link. It is NOT easy to see up in there, but if you have a Bentley, consult it to get the general layout. The lock linkage is all stout wire, running between the cylinder and door lock. It moves up and down when the cylinder triggers the lock. The "upgrade kit" consists of a new lock cylinder and a stronger link to connect to the lock mechanism. Cost about $40. The rest of the bill is for labor. Your current door key will stoll work, as you can transfer the tumblers from the old key cylinder to the new one. Again, BTDT..... The question is: how mechanical are you? This repair is NOT very difficult, but does require major door disassembly (really you separate the inner door from the outer shell, but this isn only about 8 bolts...) and some reasonably clever hands to re-assemble the door cylinder mechanism. No special tools are required other than a pair of circlip pliers with VERY small tips - and patience. If you'r reasonably handy, you can do this in 2-3 hours. If you're dangerous with tools, pay the man his $$ and be content. I have the entire procedure archived and will be glad to email to you on Monday, but I can't get at it till then. +................................................+ Al Powell, PhD Ph: 409/845-2807 Ag Communications Fax: 409/862-1202 Texas A&M University http://agcomwww.tamu.edu/agcom/satellit/alpage.htm +................................................+
