Customer Question
My 2007 Nissan Sentra...

My 2007 Nissan Sentra will not start after I disconnected the battery. How do I unlock the system

Mechanic's Assistant: Have you checked the battery, particularly the terminal connections? Are they corroded?

Yes they are fine the car cranks but it has a red car with a key in the middle flashing

Mechanic's Assistant: Are you fixing your Sentra yourself? What have you tried so far?

I changed the spark plugs and the transmission filter

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Non I think that’s it

Hey there, as long as the red car with key symbol is flashing then that is normal. If it goes solid while cranking that is bad.

If the engine cranks nice and strong then you need to check for spark do you know how?

What Customers are Saying:

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
