check under steering column to see if rod (linkage) is connected to your ignition switch. if still connected check if spring in ignition switch has broken (ignition switch is on steering column bottom side of column)
First of all, was the lock cylinder, the part where your key goes in? Or was it the ignition switch, located on the lower end of your steering column, near your feet? If this is a problem relative to a tilt steering unit, and having to replace a lock cylinder due to a lost key and thus having had to break the lock cylinder out, then yes, you will have to disassemble the column to replace the broken pot metal piece that connects your lock cylinder to your ignition switch on your steering column. These units are tricky and quite difficult to work on, unless you have a lot of patience and a very good mechanical mind or education. Now, if this is merely relative to the replacement of the actual ignition switch located near your feet on the column, then it is much simpler to deal with. Typically the problem that everyone seems to run up against is when they replace the switch, but when they turn the key, the vehicle does not turn over or even try to start. This is just an adjustment of the switch itself. loosen the 2 bolts or nuts slightly so that t is still somewhat tight, and slide the switch in small increments either direction, making certain to tighten them both again after each new slide you make until you are able to start and shut off your vehicle normally. In some cases the long rod running from the lock cylinder to the ignition switch will get bent and not work properly. ?Either et a new onr from a dealership or local wrecking yard. In the first case I addressed concerning the tilt steering column, it is a usually cheaper solution to simply go to your local wrecking yard and purchase another column than it is to have a mechanic repair or rebuild your old one.
Ignition Switch - REMOVAL & INSTALLATION (see Figure 1)
Disconnect the negative battery cable.
Remove the lower column trim panel, then remove the steering
column-to-instrument panel fasteners and carefully lower the column for
access to the switch.
Place the ignition switch in the
If the lock cylinder was removed on vehicles through 1991, the
actuating rod should be pulled up until it stops, then moved down one
detent; the switch is now in the Lock position.
Fig. 1: Adjusting the ignition switch
Remove the ignition switch-to-steering column retainers, then remove the assembly.
Before installing the ignition switch, place it in the
position, then make sure that the lock cylinder and
actuating rod are in the Locked position (1st detent from the top or 1st
detent to the right of far left detent travel).
Most replacement switches are pinned in the OFF-LOCK position for
installation purposes. If so, the pin MUST be removed after installation
or damage may occur.
Install the activating rod into the ignition switch and assemble
the switch onto the steering column. Once the switch is properly
positioned, tighten the ignition switch-to-steering column retainers to
35 inch lbs. (4.0 Nm).
When installing the ignition switch, use only the specified screws
since over length screws could impair the collapsibility of the column.
Raise the column into position and secure, then install any necessary trim plates.
Make sure the ignition is

Matchmark and remove the steering wheel.
Remove the turn signal switch from the column and allow it to hang
from the wires (leaving them connected). For details, please refer to
the procedure located earlier in this section.

For 1992-93 vehicles, remove the buzzer switch assembly.
Fig. 1: Ignition cylinder replacement
Carefully remove the lock cylinder screw and the lock cylinder. If
possible, use a magnetic tipped screwdriver on the screw in order to
help prevent the possibility of dropping it.
If the screw is dropped upon removal, it could fall into the
steering column, requiring complete disassembly in order to retrieve the
screw and prevent damage. To install:
Align and install the lock cylinder set. On vehicles through 1991
it will be necessary to rotate the switch clockwise to align the
cylinder key with the keyway in the housing.
Push the lock cylinder all the way in, then carefully install the
retaining screw. Tighten the screw to 22 inch lbs. (2.5 Nm) on tilt
columns or to 40 inch lbs. (4.5 Nm) on standard non-tilt columns.
If necessary, install the buzzer switch assembly.
Reposition and secure the turn signal switch assembly
Align and install the steering wheel.

Hello there, here are a few tips to guide you through.
Disconnect the negative battery connection cable from the battery terminal. Remove both the upper and lower steering column covers by either unscrewing them or unclipping them, depending on your car make and model. You may need to use a small pry bar to remove the upper and lower steering column covers, if so, use caution and take your time, you don't want to shatter or crack the plastic covers.
Remove the steering wheel cover and unscrew the steering wheel from the steering column, there should be six bolts securing it in place. Pull the steering wheel off the shaft slightly and make a mark on both the steering wheel and the shaft to make it easier to line up during the reassembly process. Disconnect the horn wire from the steering wheel by pulling on the boot --- not the wire itself --- to avoid any damage. Pull the steering wheel straight back and remove it entirely from the assembly.
Remove the spacer sleeve off the steering column. Remove the large center nut and washer from the steering column that secures the steering wheel adapter in place. Don't remove the steering wheel adapter until you have made a mark on it and the shaft so that you can properly realign them when reassembling. Gently remove the adapter by pulling straight back on it and set it aside.
Remove the three screws securing the stock in position. Remove the screws securing the plastic casing around the stock and take the casing off. Carefully pull the stock away from the steering column and gently guide the wires out until they have cleared the steering column, revealing the ignition switch assembly. You don't have to remove the wires from the stock; it's light enough to hang by the wires and not cause damage. Just pull out enough so that it's out of the way. In some cases, the stock will come apart in two pieces. If that's the case, slide off the first piece of the stock and unscrew the second piece, which is usually the piece that connects to your signal switch. Pull it off and bring it together with the first piece of the stock.
Remove the small plastic spacer collar around the steering column by gently prying it back inch by inch. Remove the Allen head bolt located on the underside of the steering column and pull back the assembly with the ignition switch. Unplug the wires from the back of the ignition switch and pull it away from the steering column.
Insert your key into the ignition and turn it to the locked position. Unscrew the small Phillips screw securing the ignition switch in the ignition switch assembly and slide it out. Put your new ignition switch into the ignition switch assembly and reassemble the entire steering system in the reverse order. Some ignition switch models will require you to depress a retaining pin with a small screwdriver while the key is in the locked position to remove it from the assembly. If your ignition switch is not secured with a small Phillips screw, look for the retaining pin.
First thing you need to do is determine if the problem is in the key lock or the switch. Switch is located above the steering column connected to the lock by a rod. Instructions for adjustment/install are usually in the box with the new switch. If key lock is bad, you need to disassemble the upper column under the steering wheel...Instructions can be found in either chiltons or haynes. (book is useful for many other things and a worthwhile investment at around $20.)

1994 Town Car, Crown Victoria/Grand Marquis. Workshop Manual
REMOVAL AND INSTALLATION
Disconnect battery ground cable. Remove the upper steering column shroud by removing the four or five self-tapping screws. Remove tilt steering column lock lever (if so equipped).
Remove lower steering column shroud.
Disconnect the ignition switch electrical connector.
Rotate ignition switch lock cylinder to the RUN position.
Remove the two screws retaining ignition switch.
Disengage the ignition switch from the actuator.
Installation NOTE: A new replacement ignition switch assembly will be set in the RUN position as received.
Adjust the ignition switch by sliding the carrier to the ignition switch RUN position.
Check to ensure that the ignition switch lock cylinder is in the RUN position. The RUN position is achieved by rotating the ignition switch lock cylinder approximately 90 degrees from the LOCK position.
Install the ignition switch into the actuator. It may be necessary to move the ignition switch slightly back and forth to align the ignition switch mounting holes with the lock cylinder housing threaded holes.
Install retaining screws. Tighten to 5.6-7.9 Nm (50-69 lb-in).
Connect electrical connector to ignition switch.
Connect battery ground cable. Check ignition switch for proper function, including START and ACC positions. Also, make certain that the column is in the LOCK position.
Install upper steering column shroud.
Install the lower steering column shroud and tilt steering column lock lever (if so equipped).
NOTE: The following procedure applies to vehicles that have functional ignition switch lock cylinders (11582), lock cylinder keys are available for these vehicles or the lock cylinder key numbers are known and the proper key can be made.
Disconnect battery ground cable (14301). Refer to Section 14-01 .
Turn ignition switch lock cylinder to RUN position.
Place a 3.17 mm (1/8-inch) diameter wire pin or small drift punch in hole in lower steering column shroud (3530) under ignition switch (11572). Press retaining pin while pulling out on ignition switch lock cylinder to remove it from steering column lock cylinder housing (3511).
Install ignition switch lock cylinder by turning it to RUN position. Insert ignition switch lock cylinder into steering column lock cylinder housing. Make sure ignition switch lock cylinder is fully seated and aligned in interlocking washer before turning ignition switch lock cylinder to OFF position. This will permit cylinder retaining pin to extend into steering column tube flange hole.
Rotate ignition switch lock cylinder, using lock cylinder key, to ensure correct mechanical operation in all positions.
Saw, It sounds like the accuator rod from the ignition lock cylinder to the ignition switch is broken or disconnected.
If you look near the base of the steering column you wll see the ignition switch mounted to the steering column. As you turn the key you should see the rod move up and down, if not, you will have to disassemble to figure out why.
Good luck, let me know what you find.
