no you can not

If the lock is completely frozen, you will need to replace the lock housing. The housing has come apart inside. Does your manual give instruction on how to replace the ignition lock housing? Make sure you ask the dealer for new break away bolts for the new housing.

REMOVAL

1. On models equipped with airbag, disarm airbag as described under MAINTENANCE PROCEDURES/AIRBAG SYSTEM DISARMING.
2. On all models, disconnect battery ground cable.
3. Remove ignition switch as described under STARTING AND CHARGING SYSTEMS/COMPONENT REPLACEMENT AND REPAIR PROCEDURES/IGNITION SWITCH.
4. Remove key light case from lock body, if equipped.
5. On 1989 Accord models, place ignition lock cylinder in the ACC position.
6. On except 1989 Accord, place ignition lock in the I position.
7. On all models, position suitable punch into hole on lock cylinder housing and depress pin, then remove lock cylinder from housing.

INSTALLATION

1. On 1989 Accord models, install ignition lock cylinder as follows:

1. Place ignition lock cylinder in the LOCK position.
2. Rotate key until it is almost at the ACC position, then insert lock cylinder until pin contacts housing.
3. Rotate key to ACC position, then push pin in and insert lock cylinder into housing until pin clicks into place.

1. On except 1989 Accord, install ignition lock cylinder as follows:

1. Place ignition lock cylinder in the O position.
2. Rotate key until it is almost at the I position, then insert lock cylinder until pin contacts housing.
3. Rotate key to I position, then push pin in and insert lock cylinder into housing until pin clicks into place.

SRS wire harness is routed near the ignition switch.

CAUTION:

• All SRS electrical wiring harnesses are covered with yellow outer insulation.
• Before disconnecting the SRS wire harness, install the short connector on the airbag.
• Replace the entire affected SRS harness assembly if it has an open circuit or damaged wiring.

IGNITION SWITCH

1. Remove the steering wheel, then remove the steering column covers.
2. Disconnect the 7-P connector from the under-dash fuse box.
3. Insert the key and turn it to "0."
4. Remove the 2 screws and replace the base of the switch.

hi markjones, the ignition switch can usually be removed without too much disassembly. First you will need to remove a plastic screw in the upper and lower trim covers. Seperate the covers. You should see a black plastic ring around the mechanical switch. gentley remove the ring. Next remove the rubber o-ring/band. With the key in the iginition and turned to almost to position 1, insert a heavy duty paper clip, or bmw special tool (about $30 from the dealer) into the small hole in the switch. There is a cam in the hole that needs to be twisted clockwise so the cylinder can be removed. When installing a new switch make sure to remove the little tab pice of metal that usually breaks off in the housing. Also be sure to make sure and reinstall the rubber ring/band because they are part of the ews system. If you key turns continuously, or is not able to be removed, the ignition housing and cylinder both will need replaced. Replacing the lock housing is about a 2 hour sequence and can be challenging. I would recommend a shop for that kind of repair.
