Alternator, Starter & Car Battery Replacement Services


Alternators
Your alternator powers essential systems while your engine is running. If your lights dim or your battery drains unexpectedly, it may be time for alternator repair or replacement. Our expert team will test your alternator and get you back on the road safely.

Batteries
Your car battery powers everything from the ignition to headlights. If you're jump-starting regularly or seeing a dashboard warning light, it's time to consider a car battery replacement. Our team offers fast battery testing, replacement, charging, and recycling services in Columbia. Not sure how often to replace a car battery? Most drivers should check their battery after 3 years and consider replacing by year 5-especially in extreme climates or with frequent short trips.

Starters
The starter gets your engine going. Clicking sounds or a failure to start can signal a faulty starter motor. We'll diagnose starter issues and repair or replace the component as needed to ensure reliable starts every time.


Battery FAQs


What are common mistakes when jumping a car?

The most common mistake is reversing the jumper cable connections. Always connect red to positive and black to negative. Using low-quality cables, allowing the clips to touch, or attempting to jump-start a battery with visible damage can cause serious electrical damage. When in doubt, have Walt's Service Inc. perform the jump safely.

What should I be careful of when replacing a car battery?

When replacing a car battery, avoid touching both terminals with the same tool, as this can create a dangerous short circuit. Never drop the battery, and do not reconnect the cables until the battery is securely mounted. If you're unsure about the process, let our technicians handle your battery replacement professionally.



Car Starting FAQs


How do I unlock a locked steering wheel?

Press the brake pedal and gently turn the steering wheel in the direction it moves slightly while turning the key. This relieves pressure in the steering column and allows the wheel to unlock. Never force the wheel or key. If the battery is dead or the key will not turn, consult a professional technician.

What does a failing starter sound like?

Common signs of a failing starter include a single clicking sound, grinding noises, or complete silence when turning the key. These symptoms often indicate a starter problem that should be inspected and serviced as soon as possible.

What Our Customers Are Saying

Was driving from NY to LA when my Bus started dying on the highway. Lookup the nearest VW mechanic and come here. Walt is great! He took a look at my Bus, even though it was late and he was busy-and told me the last guy who rebuilt the engine screwed up. I trusted Walt to rebuild the engine, and he did it cheaper and quicker than the first mechanic, and much better! I now have 10-15mph higher top speed and it runs a lot smoother. Driving from MO to LA I went from losing 1qt/1000 miles to losing no oil! Superb job, honest guy, nobody knows more about air-cooled VWs than he.

My daughter, a MU student, and her used 2007 high mileage Audi A4 broke down, the car was towed to Walt's. Walt called me the next day and went over his diagnostics and recommendations. He only recommended what needed to be done and did not recommend useless/costly repairs. When the car was complete, he called me with the final bill which was totally reasonable. He was timely and great to work with! I highly recommend this repair shop, it is so hard to find honest and qualified technicians and mechanics these days and Walt is truly one of the best I have ever worked with. I will definitely be back, thank you so much!

I have an old (2001) high mileage (155k+) VW Golf, and I only take it to Walt's. The staff is friendly, honest, fair, and fairly quick with repairs. They give you options and explain the pros and cons of optional repairs. They keep my old Golf running well, with fair costs for repairs. I would (and have) recommended to anyone with a VW or similar German car.

I had my MINI Cooper serviced here. These guys are great. They showed me everything about my car (as I know nothing about cars). The Baron MINI in Kansas City told me I needed new front and back brakes and rotors. After showing me how much brake pad I had left on the back brakes, the guy at Walt's said "that's nuts and these should last at least another year". They also did quality work and cost a couple hundred bucks less! I am very pleased!

I would not take my car anywhere else. They are honest, friendly and work with you to make the best/most cost effective repair solutions.

Great people and service. They went above and beyond in order to help me resolve a problem with my 2011 Audi S5. Definitely plan on going back.
