Hello and welcome to Just, Super mechanic here. About your vehicle.

Is it stuck in park?

Do you hear a clicking sound in the console, when you step on the brake with the key on?

Do the stop lights work?

You will want to check the fuses,

There has been a service bulletin for that type of concern. Here is what it states.


Bulletin No.: 08-07-30-007B

Date: June 08, 2009

Subject: EI08045 - Key Cannot Be Removed from Ignition with Gear Selector in Park, Shifter Cannot Be Moved from Park Position (Repair/Reroute Brake Transmission Shift Interlock (BTSI) Solenoid Harness)



2007-2009 Chevrolet Impala Supercede:This bulletin is being revised to end the need for information from the field and provide repair information. Please discard Corporate Bulletin Number 08-07-30-007A (Section 07 - Transmission/Transaxle).


Some customers may comment on either of the following conditions:

- The key cannot be removed from the ignition.
- The transmission gear selector (shifter) cannot be moved out of the PARK position.


This condition may be caused by an incorrectly routed brake transmission shift interlock (BTSI) solenoid harness which can make it difficult to install. In some instances, the wiring looms are tangled, causing stress on the wires in the connector at the BTSI. If the BTSI harness is routed incorrectly, it may also result in a wire pinching issue.


DO NOT use force to move the gear selector (shifter). Using force may cause damage to the BTSI.

Inspection/Routing and Repair of the BTSI Wiring Harness/Connector

1. Check for wire damage at the BTSI connector terminal ends. Refer to SI for repair procedures.
2. For very intermittent issues, check the BTSI wire harness individual circuits for broken or crimped wires. Refer to SI for repair procedures.

3. Inspect the routing of the wiring harness leading to the BTSI connector. The illustrations above show the BTSI harness routed incorrectly.

4. Reroute the wiring to create available slack and avoid future occurrences.

how can i get to harness myself
Expert:  Super Mechanic replied 6 years ago.
That would be under the console with a floor shifter and in the steering column with a column shift. Most of them have the floor shifter, let me get the instructions for that, BRB
