Chevy 2005 equinox, our keys are locked inside and we have no spare. How do we open the car or where can we get a replacement key?

Your best bet would be to locate a locksmith, Pop-A-Lock is a common company in the south and central states. They have tools that can open the door without causing damage to the interior controls. Your second choice would be to call the Non-Emergency police number and ask if by chance their officers carry a device called a "Slim Jim" which some departments will allow officers toe carry to assist motorist. Some departments do allow this as a courtesy service and some don't but in teh case they don't they may be able to give you a number of a dependable locksmith service. As far as getting a spare made that will depend on whether you have the security key or a regular key. Security keys have chips in them to protect against theft and did not become standard issue in most mid to high end vehicles until 2007 but were available as an option on vehicles starting in 2000.
