Fantastic servicePosted on Google Sean BrennanTrustindex verifies that the original source of the review is Google. Highly recommend Nick! After being let down by multiple auto locksmiths who either didn't show up—or in one case, took a deposit and vanished—finding Nick was a massive relief. From the initial contact, he was honest, professional, and kept me updated throughout. He arrived when he said he would, did fantastic work, and charged a very fair price with zero hidden fees. A genuine, reliable professional.Posted on Google Ian ThrussellTrustindex verifies that the original source of the review is Google. Have called Nick twice now for car keys.Would recommend.Turned up when he said he would .Great job thank you.Posted on Google Abi Walker- SpiersTrustindex verifies that the original source of the review is Google. Locked myself out of my car. Locksmith came out super quick, 45 minutes, and had the car open very quickly. Great communication, friendly service, very reasonable price to be back in my car so quick. Would absolutely recommend / use againPosted on Google Deborah AmottTrustindex verifies that the original source of the review is Google. Nick was amazing regarding spare keys for our Micra and Astra. Both were replaced at very reasonable cost, and the bonus being Nick came out to us, which saved a half hour journey each way. When our main Astra key then started playing up, Nick tried to help via messages, but we weren't confident to try the changes ourselves. So Nick visited again and we did end up needing a brand new key as the original was badly damaged. Again, done at a very reasonable cost. Nick is helpful, friendly and so easy to deal with. We would highly recommend.Posted on Google Lynne DeaconTrustindex verifies that the original source of the review is Google. Mick was fabulous. From call to key took an hour.

Nick did a great job replacing the proximity assembly on my Nissan Micra – a job that several other mechanics refused to take on! He has a logical engineer's brain and approached the problem methodically, explaining the likely chances of success at every stage of what turned out to be a complicated repair.
