Having trouble locking or unlocking your car door?
Look, you’re not the only one. We get folks pulling up from all over Hamilton – Te Awamutu, Ngaruawahia, Matangi – because a sticky car door lock is doing their head in. Sometimes it’s that key fob refusing to do its job in the middle of The Base carpark, or a classic old Corolla where the key’s getting harder to turn with all the potholes and mud we deal with on Bader Drive or Cobham Drive.
Door lock problems are a pain, whether your ride’s a late-model Kia Sorento or you’re cruising in something European like a Peugeot 308. Especially with these stop-start trips across Hamilton traffic, rough speed bumps in Fairfield or Avalon, and that classic Waikato combo of foggy winters and baking-hot summers – all of it takes a toll on locks and electrical bits over the years.
Modern fob key giving you grief?
Most newer cars – think Mazda Demio, Toyota RAV4, even the odd Skoda Superb we see in the workshop – have key fobs that open and close your doors or boot with the push of a button. Magic, until it’s not.

Key fob battery is flat
Half the time, it’s just a dead battery in your fob. Easy fix – swing by Grimmer Motors, we can swap the battery and have you away down Te Rapa straight in ten minutes.
-
Fob itself is stuffed
If you’ve changed the battery and it’s still not playing ball, the fob might have carked it. Electronics don’t love wet Hamilton winters or being dropped under the seat. Bring it in, our techs can quickly check if it’s sending a signal and if not, we can sort a new one for you. Here’s more on the power door lock radiofrequency systems we see all the time.
-
Blown fuse or dodgy actuator
Sometimes, you’ll find one door’s not working but the rest are sweet. Odds are it’s just a fuse, or the door lock actuator’s packed up. Sometimes it’s a fiddly fix – pulling the door apart and having a squiz at the internals – but we do them all the time.
-
Faulty locking relay
Power locks working on and off? That’s a classic sign your locking relay is on the way out. Happens more than you’d think, especially in those Euro wagons. More signs to spot are in this guide.
Cars with normal keys not locking or unlocking?
If you’re driving an Isuzu Bighorn, old Suzuki Swift, or a Honda Accord, it might be good old-fashioned key & barrel issues.
-
Latch damage
Bashed your latch parking up on Anglesea Street, or had someone try to break in? If the latch is bent or knocked out of alignment, the lock can seize up in the locked position. Usually means the lock/panel has to come off and sometimes a new bit chucked in.
-
Broken or stuck key
Not as rare as you’d think – we’ve fished plenty of broken keys out of locks, especially after a muddy Saturday at Gower Park. We can get a replacement sorted easy as, no dramas.
-
Dirt, rust or jamming
Over time, thanks to all the dust up around Rototuna or the winter rain, muck gets into locks. Next thing you know, your key won’t turn or it gets jammed solid. Often, a spray of lube and some patience does the trick. Otherwise, here are some more tips before you call it quits.
-
Broken connections inside the door
If the interior lock switch or handle isn’t quite clicking, often it’s a link or rod come loose inside the door after years of rattling up and down Kahikatea Drive. That’s a job to pop open and reconnect what’s come apart.
Why bother fixing your locks?
A dodgy car door lock might not leave you on the side of Morrinsville Road, but it’ll fail a WOF Hamilton check and leave your car an easy target for thieves, or be a real hassle if you’re wrangling the kids in and out on a wet morning in Dinsdale. Best to sort it early before little problems turn big.
