We had a lock fitted in December. Recently it went faulty and we were locked out of our house at 7.30am! We called Ajax, they were here by 8am helped us get back in, and then came back later with a replacement for the faulty part without any excuses. A fantastic follow-up service. Thank you for being there when we needed you.

Please learn how to update your times on Google. If you are closed, put it on your Google profile. A sign on the door is not helpful when you have to drive there just to see it. Its 2020 - Google maps has been around 15 years!

Asked for two padlock keys to be cut. Neither of them worked - will not open the lock. Then asked for a replacement car key; they told me it had a chip in it which would cost over $150. Paid for this and a simple key with no chip for $10. Both keys work to open and start the car - no need for the higher price unit. Wondered how they could copy the "chip" so quickly...Stay away from this crowd!

The key works, was told I can't pay with card ($5.50) and that the limit it $15 (this is not advertised in store). This practice is banned by the ACCC, customers have a right to pay with card if it is offered. Not even the lady across the road at the ezymart has a minimum for a pack of pk gum. A simple sign at the counter informing customers of a percentage surcharge on purchases under a specific amount would be legal and help avoid negative experiences.
