Easy install fit perfect and got my grandsons car out of my carport!????
It was the exact part that I needed and got here right on time.
I was having trouble with the car starting occasionally, and this little part fixed it. The best part is that there are also some dash lights I never knew were, therefore, not working. Win. Now, for the complaint to 1A Auto, could you have a better way to know what way you are shipping?
I was expecting a real headache to replace ignition switch, Perfect fit new switch installed 20 minutes start to finish. Highly recommend 1A AUTO
Great shipping time, super low price and whoppee works like new. Glad to find your company Thanks ??
Arrived on time. Fit and worked as advertised. My car doesn't shut off anymore. I shopped around and A1Auto had the best price for this part.
I recently had to replace the ignition switch on my daughters 00 Cavalier. The price was ridiculously cheap compared to our local parts stores. More than $35 less! Free Shipping and the part arrived a day early! The online How To Video for reference made it an easy swap taking less than 30 minutes! Thank You 1aauto!!!!
Perfect fit easy replacement thank you very much
I sure appreciate the helpful videos on 1AAuto and the detailed installation instructions. Most importantly, the bit of info that told me Chevy uses an E4 external star nut on their ignition switches. The hardest part of the job was removing the rear nut (there are only 2 holding it on ) as it was tucked behind the switch and needed a swivel socket and some finagiling to get the socket on it. The switch worked perfectly and didn't mess with the anti theft settings. Another fine repair with the help of 1AAuto.
Very happy with the purchase and especially with the price. Quick shipping and reasonable cost also. I strongly recommend this company, you can shop with confidence!

Thank you for your inquiry! This is just the switch, not the key cylinder. If you were switching out the cylinder, then yes, you would need to get a new key or have the cylinder tumblers set to match the old key.
