Standard Brand ignition lock cylinder recodingMat for a 1999 Sonoma gmc. Installed a new ignition lock cylinder, my gears are locked. Do I need to recode it, to get the gears to unlock


There is a shifter unlock cable( not plug in or loose). The only thing with the cylinder replacement may be a relearn for security. This kills the engine, doesn't mess with the shifter or transmission.

How to remove my Keys from 2003 envoy they are stuck


Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column as an added safety feature. The ignition lock cylinder control actuators purpose is to prevent the steering wheel from being locked when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control acutator, and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control acutator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column. GM has had some problems with this , If you have the console shifter there is a micro switch that when put into park a linkage pushes on this micro switch closing the circuit to ignition lock cylinder control actuator allowing you to remove your key ! These linkages fall out causing this problem ,an have electrical wiring problems as well ! I fixed a 2006 Chevy cobalt that had this same problem by getting a used shifter assembly at the auto salvage year ! cost $20.00 . There mite be a access hole under the bottom of the steering column with a release button up inside !

Need to rpl ignition lock 98 GMC K1500 PU


Most ignitions you will need to remove the plastic shroud around the steering colum. Have a good look at the complete barel & mount & you should find a small hole. When the key is in a certain position (usualy accessories) there is a little pin in that hole. You push the pin in with small allenkey, jewler screwdriver etc... & the barel will just slide out.

2001 gmc yukon xl key in ignition won't turn to start at all.


The tumblers in the ignition lock may be seized, try cleaning it out first with a small spray of WD40 and try the spare ignition keys. The keys it self may be too worn down for the tumblers in the lock and if you have lots of other keys on your key chains, this will promote the lock to wear out quicker. Good luck and hope this helps and try turning the steering where back and forth as you try to turn the ignition key.

2000 Jimmy , put in park , turn off key & key wont come out of ignition.


Does the transmission work in all 4 gears? I've seen bad ignition switches cause this. Not the ignition lock cylinder, the electrical switch.

Ignition lock -98 dodge neon


Sounds like the ignition cylinder is jambed, if you remove the covers and put the key in, you might be able to turn it with pliers, just turn it to the accessories position, then there is a small metal clip that pushes in, push it in and pull the lock cylinder out of place, get a new one from the dealer and reverse to install. If it's above you, your dealer can help, usually about an hours labour or so.
Hope that helps, Good luck
