Transponders

We Repair, Replace, and Program Transponder Keys

Transponder keys, also known as chip keys, are designed with an embedded RFID chip that communicates with your vehicle’s immobilizer system. This added security prevents unauthorized access and has made modern vehicles much safer from theft.

However, when a transponder key stops working, gets damaged, or is lost, your vehicle may not start at all. Without proper programming, even a newly cut key won’t function correctly.

Signs You May Need Transponder Key Service

Their tech came out to our house on a rainy evening (after dark) to deliver (and program) a replacement of FOB & ignition key. Everything went well. On time, courteous, professional. Thanks a lot!

Really quick same day service on my BMW programming two new key fobs. Communication was top notch. They moved as quickly as they could to get through the encryption process. The service guy who came out Sergie was polite, personable and patient. I’d recommend them to a friend. Thank you guys!

Josiah M.

They provided fair deals with providing 2 spares for my motorcycle key (2015 cbr500r). I met with Dereck and he finished making my duplicates in less than 15 minutes. Dereck was a calm and understanding technician. Compared to other prices, a company called Fast Key charged me double than what Alohomora offered. I'm definitely going back if I lose any more keys.

Theresa C.

5 STARS! Very grateful for their help in replacing my key fob. They were friendly, communicative, and prompt - and half the cost of the dealership replacement. Thank you

David L.

Asked for a bid and was immediately contacted with a fair price. Were more than accommodating for us to receive OEM Fob in mail. Will follow up on services rendered after performance.

Jon Y.

After some time, Alohomora reached out to me and apologized for the last service and refunded my money. I am updating my review because of this good will, but I'm not erasing my experience as I feel it's important to share with others. The company has not mentioned anything about how they warrant their work and I feel that is important for consumers to have reassurance with this type of work. Make sure to ask and get it in writing and keep those receipts! Best of luck.

David S.

Derek is the bomb! Showed up after hours to make sure my Garage door was working after it jammed open. He observed that it was in warranty also. He really took the time to look at it and check for any abnormalities. I recommend Derek for sure! Door works excellent now.

Alison T.

Our 1990s garage door opener opened its last door and gave up trying to open any more. And while we didn't reach out to Alohomora directly, they sent a contractor out to help. They had what we needed and we were able to negotiate down to a fair price to replace on the spot. It's been working great for the past few months; hope we get another 30 years out of it hahah.

Katherine F.

They changed our locks and installed a new garage door after we moved. The garage door stopped working a few months later, but they sent a technician to fix it within an hour for no charge.

Kelly G.

I went to take the trash out and Derek was installing a new lock on our neighbor's mailbox. I chatted with him for a minute, then I remembered that the padlock on the spare tire case of our Toyota Rav4 was rusted closed. I asked him if he might have a pair of bolt cutters. He didn't but said he had a grinder that would do the trick. It did the trick, and no charge. I really appreciated it, and now I don't have to think about it anymore. Thank you, Derek!

Dawn S.

Alohomora Locksmith provided friendly and speedy service when I was locked out of my place. Matt was a great technician, and I would definitely contact Alohomora Locksmith again if I have any more issues. I highly recommend this company!
