Husband lost key to car and I need to know how I can remove the ignition so it can be replaced

Here is an idea; call the local dealer and get a new key. The serial number of the auto should help you do this.

Replacing an ignition switch is not something the average car owner should do. Making any number of mistakes will cause loss of control while driving, damage to linkage. If for any reason the steering wheel needs to be removed on a car that has an airbag, injury or death can result. This should only be done by someone with experience with this kind of work.

Cirrus, Stratus, Sebring Convertible and Breeze CAUTION
The Supplemental Inflatable Restraint (SIR) system must be disarmed before working around the steering column. Failure to do so may cause accidental deployment of the air bags, resulting in unnecessary SIR system repairs and/or personal injury.

3. Pull down the lower steering column shroud enough to access the lock cylinder retaining tab.
4. Turn the ignition key to the RUN position.
5. Insert a small prying tool into the tab access hole and depress the tab. Fig. 1: Depress the retaining tab and remove the lock cylinder

10. Lightly pull on the ignition lock to make sure it has engaged the retaining tab.
