Product Description

The number one complaint vehicle owners have is bringing their car or truck to a repair shop with the fear of being taken advantage of. CodeKey is the solution to this fear. CodeKey is a sophisticated but simple, easy to use device designed to unlock the mystery of why your vehicles "Check Engine" light is illuminated. With CodeKey, you can be your own "vehicle doctor" and diagnose what is wrong with it. You may not always be able to fix it yourself, but you will know what part or system of your vehicle is not working properly, allowing you to make a more educated decision on who should repair it- potentially saving money by being more informed. CodeKey is designed to work on all '96 and newer model vehicles.

The check engine light on my truck came on. A local repair shop quoted me $92 to diagnose the problem and said that it would take about an hour.

For half the cost of the shop diagnosis fee, I figured this code reader was worth a try. Use couldn't be simpler - find the OBD-II port under the dash, turn the key to the "on" position, plug the code reader into the port, and press the "read" button.

It only took a couple of seconds to read the codes and tell me why the check engine light came on.

Build quality seems to be pretty good. The cord appears to be heavy duty and the plastic housing seems sturdy. And the LCD screen is backlit to make it easy to read in the dark. And to top it off, the price was a lot less than having a shop read the codes. Now I can read any code that comes up on any of my cars!

I purchased my CodeKey at Costco and it worked perfectly on my 2007 Honda Element. In case you don't like to read instruction manuals, here is the simple procedure:

Turn ignition ON (but don't start the car). Plug the CodeKey into the vehicle's computer connector. Press and release the Read button. That's IT! CodeKey will display, "Searching...." and within a few seconds you will have a summary of the codes found. Continue to press and release the Read button to scroll through the codes and the code descriptions.

If you wish to delete a code, perform the read instructions above and scroll to the code you would like to delete. Press and hold the Delete button until a confirmation screen appears (about 3 seconds). Release the Delete button. Now press and release the Delete button to delete the code or press and release the Read button to cancel and not delete the code.

Thumbs up for this great product!

I have had the Check Engine Light (CEL) come on in our 2003 VW Passat and GTI several times. Using the CodeKey, I check the code and then erase the code from the system. Using Google to search for the code, I can find out what is wrong and determine if I can fix it myself. Often times, after resetting the code the CEL does not come back on. The one time I could not get the code to stay off, I was able to take it to my mechanic and tell him what the problem was. Mechanics are less likely to do more work than required when you can diagnose the problem yourself. I highly recommend this diagnostic tool. It will pay for itself the first time you use it.

A week back check engine light came on my 2004 Honda Accord. I bought codekey reader from costco, hooked up to the OBDII port, and read the codes successfully. Initially I had trouble locating the obdii port. After a call to Honda dealer I figured out the exact location of the port - driver side, under the dashboard, left hand side, just above the fuse box. I had to literally put my head on the car mat to see the position of the port. It took a while for the codekey to read and display the codes. Good part - it not only displays the codes, but also the description. In my case the error was 'fuel cap loose'.

I checked the cap, in fact it is very loose. Tightened cap, read the code again, and erased it. Started the engine, and I don't see the check engine light now.

Auto Repair shop quoted $85 to diagnose the check engine light.

It is really a great device at less than half price of the diagnosis cost. Check Engine light mystery is demystified without going to a repair shop!!

ARRIVED QUICKLY AND PERFECT-----I PUT THE DEVICE TO WORK RIGHT AWAY AS I INSTALLED A RACING EXHAUST ON ONE OF MY DODGE VIPERS AND THE ENGINE CHECK LIGHT WAS COMING ON. I WAS ABLE TO GET THE
DIAGNOSTIC CODES AND WAS ALERTED TO INEFFICIENT CAT PERFORMANCE. THE DEVICE CLEARED THE DASH LIGHT AND THE RACING COMPANY SENT REPLACEMENT CATS. DEVICE WORKS WELL AND IS EASY TO USE AND
ACCURATE----------GETS A FIVE STAR AND HIGH RECOMMEND AS TO GOOD QUALITY AND REASONABLE COST AND THIS DEVICE SHOULD BE PART OF EVERY CAR OWNER'S GARAGE. ALSO, I PURCHASED A SECOND ONE AS A GIFT.

Easy to use and works perfectly. The hardest part is finding where the port to plug it into on the car. :)
Able to erase diagnostic codes off the car to see if they appear again after fixing faults.
