Hello Andrea. Nice to hear from you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Was anything done to your vehicle recently that may have caused this issue to occur?

No

Do you have a second key to try at all to see if it will start and run when using it?

I only have 1 key

Thank you for your reply and that information as this does help me better understand the situation. Please give me one moment to type out some info for you. I’ll be right back! Thank you for holding Andrea! The immobilizer can become active anytime the computer detects a fault with one of the vehicle's security components. It will prevent the engine from starting. This type of fault is commonly caused by a failed electronic key that has to be replaced. In order to determine for sure that the key itself has to be replaced and to see if anything else has to be replaced what needs to be done is to have a fully compatible scan tool plugged into your vehicle's data port that can read all of the computers in your vehicle to see if any fault codes are stored with this issue. Once this has been done, any codes that come up can then be diagnosed to help pinpoint and repair this issue. This will require the use of a high-end scan tool that can read all of your vehicle's computers. If you do not have a scan tool to check the fault codes yourself a shop or dealer can check the fault codes as well as diagnose the issue for about a 1-hour labor charge ( around $100 ). The cost to repair the problem varies as it depends on which component has failed that requires repair or replacement. If the key has to be replaced a dealer can order one in new for you and program it to your vehicle for around $300. A local locksmith can sometimes obtain the key for you as well and program it for around half the cost. The codes do need to be read out to help determine for sure which component has to be replaced to resolve this issue. Unfortunately, there is no way to get around this issue or bypass it to allow your engine to start and run.

I'm going to hit the unlock button then see if that helps

In some cases locking and unlocking the doors with the key/remote will allow the security system to disable. If this does not work though, then the codes will need to be read out to help identify if the key or any other security component has to be replaced and programmed to resolve this issue.
