Having Passkey III Issues. 2000 Buick LeSabre Custom. I have
I have a 2000 Buick Lesabre, VIN# 1G4HP54K3Y4112959.It has Passkey 3, the keys are original factory with PK3 stamped on them. This problem is intermittent, started about 6 months ago, and is progressively getting worse.Here's what's happening: Insert the key and attempt to start, dash lights up as normal, but starter won't engage (nothing happens). When this occurs, the security light is on, solid. Sometimes, the security light stays on even after it starts.I replaced the Anti-Theft Module (Exciter/Receiver) surrounding the key cylinder with another one from the junk yard, same part # (Delco PN: 16266469) and the ignition switch (not the cylinder) from a junk yard, then performed the 30 minute relearn (3 – 10 minute cycles).The still symptoms continue as described.DTC Codes are (all in History Codes): B1009 – Undocumented B1327 – Undocumented B2734 – Coded key Controlled Memory Failure B2960 – Security system sensor data incorrect but valid B3031 – Security System controller in Learn mode B3055 – No transponder Modulation or No TransponderI'm ok with buying new parts, but as they are expensive I'd like to have a better idea of what to replace. Can you help? … read more
